SO many issues: can't pay via EFT, can't contact, unauthorized fee

- Been trying to pay my account via EFT and keep getting an error that they cannot connect to the bank. - There's no live chat or email, only contact via phone call. When I tried, nobody called me back and I can't just randomly take calls during the day at work. And nobody answers 10123 and 081180. - Unauthorised subscription fee in the middle of the month when my contract should be concluded. Tried to find out why but can't contact anyone.
