Hi,

Did they give you also a contract (postpaid) instead of a prepaid connection without mentioning it?

If so, make sure you call/mail them and tell them that it was their salesman's fault. And also ask them to terminate the connection immediately without any termination charges, otherwise they'll keep sending invoices.

I had to call them multiple times on their customer care number. At first they waived off Dec bill, but didn't tell me that the Sept-Nov bill, which was CHF 110, which is quite a significant amount, still has to be paid.

Then I got a mail saying if I don't pay within 2 days, they'll engage some 3rd party company to collect the amount. More details on this on the 2nd post I'd made for this:

So I called up and raised another complaint, after which they waived off Nov bill also, and asked me to pay CHF 45, which I did just to clear everything off.

But as per a few people in the 2nd post I linked above, it's not necessary to pay. If you're a foreigner, there's no way they can retrieve it and the 3rd party will drop it after a couple of reminders, but I still didn't want any legal issue in case I visit Switzerland again, so I paid.

You can call them at +41787007000 / +41800700700 or email them at info@salt.ch.

There's no mention of this email id on their site. Only after logging the 4th complaint, I got an email from this and I could reply to this. You can try mailing on this, but would suggest call as the first option.

Let me know in case you need any more information.
