Forcing people to pay via debit orders

On the 15th of July my line was suspended due to the fact that I pay via electronic transfers monthly. I Spoke to Mfundo Kunene after both my lines were suspended, she confirmed my account was not in arrears and that they were receiving payment monthly on the 25th. However since I pay via electronic transfer I would have to call them monthly to arrange for her not to suspend my line. This is hogwash, absolutely disgusting literally forcing me to pay via debit order!
