Bad Service, Unacceptable assumptions & unfair Treatment.

I prematurely cancelled my contracts with Vodacom on the 14th of November, now, a month later I receive an invoice for an outstanding amount. When calling Vodacom customer care and being transferred from department to department and 59 minutes later it was finally established that this is the invoice that was generated by Vodacom on the 3rd of November. When i did the premature cancellation inquiry i was told that the consultant will send me a quote for each of the contracts, after the quotes were received the call ended, i completed the payment for the full amount and sent the signed quotes along with the proof of payment to the Vodacom Cancellations department. I have received an sms stating the contracts has been migrated to prepaid. Now i am being told that the invoice for the month of November was not included on the Premature Cancellation quote, I was not aware of this nor did any of the consultants i have spoken to, notified me of this on the quote the un-billed usage cost was R0.00 as well as the outstanding account balance therefore i assumed that the accounts has been closed and i am never to hear from Vodacom again. I feel that i, the consumer, has been treated unfairly, i am highly disgusted with the fact that there was not proper communication from Vodacom's side and i was not advised that the quote does not include the settlement amount, any logical person would assume that that if you request the settlement balance it would include the outstanding balances which is not the case with Vodacom. All the above would have been avoided should they just have communicated properly. I feel it is highly unprofessional that Vodacom assumes that the consumer knows that the quote does not include invoices that has already been issued, my logical thinking is that when you issue a settlement quote you go into the account get the outstanding balance get the premature cancellation cost and quote the client the full amount or atleast notify the client that they can not add the full amount due to the fact that the invoices has been issued. This is so unfair of Vodacom to expect me to pay this now as there was a reason for the cancellation in the first place.
