Vodacom fibre terrible service

Poor pathetic service from vodacom fibre, besides all the issues with their inferior H500 routers... they remove our debit order without notifying us then cancel our fibre due to non payment..... now they tell me even if we pay the arrears we still have to apply for a new account with them... I really don't understand, I expected more from vodacom, I'm so disappointed.. how can u cancel my debit order without telling me then cancel my contract for nonpayment??? How was I supposed to know if u didn't notify me??? I've been fighting with ur consultants whole week already
