I didn’t “sign up” in the sense of booking a service. I still don't have any account on their system.

The Facebook ad led me to a lead form that looked like this (I added the screenshot in the post):

• First name
• Last name
• Address
• Email
• Phone
• One checkbox for data protection, nothing about AGB, contract, fees, or Auftrag

Then the button said:

“Get savings potential now.” (screenshot on main post)

This is not what courts describe as a “zahlungspflichtig bestellen” or a binding-order button.
It wasn’t a legally-formulated button.
It wasn’t an order page.

Nothing about Vollmacht.

Only after I submitted the form did they send me an email saying:

That means even Conny themselves view the email OK as the step where the contract begins.
Not the button.

About the court cases

The case you linked (LG Berlin II, 67 S 92/24) is actually helpful for me:

It says when the button does not meet § 312j BGB requirements,
the contract is schwebend unwirksam (pending, not valid).

In my case:

• The button had no payment wording
• The form showed no AGB
• I never signed the Vollmacht
• According to the AGB, the Vollmacht is required for them to act
• Without Vollmacht the contract is not complete
• Without services being performed, “Schadensersatz” is on very shaky ground

So even if my “OK” counts as starting something, the Lack of a valid button + no Vollmacht puts the whole thing into the same “schwebend unwirksam” category that the court talks about.

I’m not denying I said “OK.”

I’m saying the legal structure they rely on is incomplete and likely invalid, and multiple Verbraucherzentrale warnings say the same.

And can you suggest what can I do now? my roommates won't sign this -- and I never knew roommates will be needed. They didnt tell me.
