DISGRACEFUL CUSTOMER SERVICE

I received an SMS this morning at 09h47 saying that I have an outstanding amount owing and if I don't pay it immediately my service will be suspended. I straight away went to my supersonic account - tried to log in - apparently my details are incorrect! Asked for a password reset link, a pop up comes up to say that a link will be sent within 5 min - well that was almost 2 hours ago - nothing has arrived. Try another email address was their next option - I don't have one!!!!!!! Then their BOT told me that it really has nothing to do with Supersonic I need to contact my FNO. So Supersonic what have you got to say here? You don't have the best reputation and clearly you don't have the best technology either because my password has been saved to my login for my account and the error message reads - Invalid! How are you going to fix this? and how many hours/days/months am I going to have to wait for action.
