Telkom does not make it easy to contact them.

Telekom makes it impossible to contact them. When I phone and hold on the phone drops, when I try and use the login self service there is no option to change the bank debit order, when I use the help chat they kick me out after I gave my ID. Name. Number. And bank. Because I don't know the phone number for my data Sim which is in a mobile wifi router. I have tried the whole day.
