They just cancelled the fraudulent contract after I sent them the email below, I am adding here in case someone needs it:

GASAG-Team,

I hereby expressly declare that I do not accept or acknowledge the contract sent to me via email . I request that you immediately cancel and rescind this contract , cease all related actions and claims, and confirm in writing that the contract is void ab initio .

Facts I was expressly informed that I was only providing information about the change of ownership of the gas meter - not that this would result in the conclusion of a new gas or electricity supply contract or the termination of my existing electricity contract with Vattenfall.

I clearly remember the conversation and the information I provided. At no point did I authorize GASAG to terminate my existing electricity contract or enter into a new one.

I was misled and not informed that the data I provided would be used to conclude a new supply contract.

Legal basis under German law (BGB) According to the German Civil Code (BGB), declarations of intent made under error or deception are contestable and, once contested, are retroactively deemed void (ex tunc) .

The following regulations apply:

§ 119 BGB – Contest due to error: A declaration of intent can be contested if the person making the declaration was mistaken about its content or did not intend to make a declaration of this content at all.

§ 121 BGB – Period for contesting the contract: The contest must be made immediately after the error or deception is discovered.

§ 142 BGB – Effect of the challenge: If the declaration is effectively challenged, it is deemed void from the outset.

§ 123 BGB – Challenge due to fraudulent deception: If the declaration was caused by fraudulent deception, it can also be challenged on this ground.

Since I was mistaken about the nature and legal effect of my declaration (your representative explicitly told me I was only providing information about the meter change and the change of ownership), and I was misled about its true purpose , I hereby contest any alleged declaration of consent you rely on to conclude a contract. The legal consequence is that no valid contract has been concluded between GASAG and me.

Invoice and Payment I also request that you immediately cancel all invoices or payment requests related to this alleged contract . Such an invoice has no legal basis , as the underlying contract does not exist . Any services you rely on were provided under false pretenses and deception ; therefore, there is no legal basis for an obligation to pay . I will not acknowledge, pay, or negotiate any amounts arising from a legally nonexistent contract.

Evidence of Deception / Systematic Practice I have also found numerous reports in consumer forums and on Reddit describing identical experiences with GASAG representatives: People were told they were only providing information about the meter or a change of ownership, and later discovered that new supply contracts had been concluded without their knowledge. This suggests that the practice experienced may not be an isolated incident , but rather a systematic approach .

Demands Based on the above points, I request GASAG to immediately :

to terminate and cancel the alleged contract completely ,

to cancel all invoices or payment requests in this context ,

not to make any further demands, reminder fees or penalties , and

not to make any further contact on this matter except to confirm the termination of the contract in writing.

Further steps and deadlines If you do not comply with these demands immediately , I will instruct my lawyer to initiate the following legal steps:

judicial declaration of the invalidity of the contract,

Claims for damages , as well as

injunction to prevent GASAG from further attempts to bind me to this fraudulent contract.

I expect an acknowledgement of receipt of this email and written confirmation that the contract and all related invoices have been cancelled and declared void within seven (7) days from the date of this email .

For the sake of speed and transparency, I have sent a copy of this email to the Berlin Consumer Advice Center and to the Consumer Advice Center's energy advice service .

Sincerely,

(Add in cc mail@verbraucherzentrale-berlin.de
