Inept service

I am HIGHLY angered by the rude service I received from a VVM Collections consultant

It started with her continuously interrupting me, while I was trying to get my query/question across, when I BLEW up and she 'allowed' me to finish what I was asking she then responded with 'Oh Are you finished'. I then greeted and ended the call It is unacceptable that this is the treatment that your customers receive

I cancelled my contract in September and paid the amount I was told to pay. Then on the 9th October I received an account for R8.64. My husband answered a call yesterday on his personal number (and thought that they were calling about his account, the amount owed was R273 which they then proceeded to set up a debit order for OFF MY BANK ACCOUNT - I did not authorise this as I know that his vodacom account is in the region of R900 and is debited every month from his bank account and I 100% thought this could be a **** and therefore did not authorise) This morning on receipt of a sms (to his number), I looked into the account number and saw that it was for the aforementioned cancelled contract.

Can someone explain to me HOW in less than a month a R8.64 account is now R273 and WHY was it handed over to a debt collector

ALSO, I have tried contacting via call centre but because the number is no longer on your system, its impossible
