Terrible Customer Service

Vodacom has terrible service & is very disappointing. I contacted their call center two weeks to cancel my contract. I was told to pay the balance, of which I did last week. Today I called for cancelation, to my surprise the consultant gave accounts number to call. This accounts collection number has automated voice note, when I enter the Vodacom cell number the system can't find it but at cancelations they see it.

Can Vodacom this useless, this is disgusting & up to now I have not been helped!!!! Yeeer
