Stop lycamobile auto renew

I have an old lycamobile sim and had the 500 mb data pack. I no longer use the sim and would like to stop the auto-renewal of the data pack.

I don't have the login info for the website and I've tried mailing customer care with no success.

How should I try to stop the auto-renewal?

Since you live in Zürich you could try your luck at their office on the Hermetschloostrasse 73, bring the Sim, contract and your ID or whatever would be relevant along.

well you know the number of your phone and you can set a new password if you have forgotten it!?

*190# can stop the auto renew.

I think I occasionally cancelled auto renewal of the wrong bundle. Does anybody know if it's possible to re-enable auto renewal?

Yes it‘s possible to autorenew the wrong bundle again...

But how? I can't find a single link in Google covering this topic. The code *190# only works for disabling auto renewal.
