Hello, I have been using MagentaZuhause M for the past few years and today I submitted the form on this website to change to MagentaZuhause L.

Unfortunately on the form I entered the wrong Vorwahl for my Handy number, I typed 0178 but it should have been 0176.  After submitting the form it said it sent a confirmation code to my Handy, which of course I didn't receive.  There was also an 'uberspringen' option so I clicked that, and it seems that everything is fine, but I didn't get a confirmation email either.

Is there any way to change the Handy number associated with my tariff change request?
