Terrible service from Call centre staff and Supervisor

I called in every week to make arrangements for my debit order to be told that it would go off and it did not. Today I received a sms's stating im in arrears when I called in 3 times weekly to ensure Vodacom debits me correctly. Today I called the call centre and spoke to Tebogo from Subscriber collections who was extremely rude to me, I requested to speak to her manager she transferred me to Ashwin Abrahams who refused to give me her details and seemed to be protecting the staff member who was rude to me. I have been a client of Vodacom for over 10 year and have never been treated like this. This was my worst experience with Vodacom I always get exceptional service yet today my issue was not resolved and I was spoken to in such a terrible manner even worse treated by the manager. Very disappointed in Vodacom
