Pathetic service

Utterly disgusting and disappointing service, I was contacted in November regarding my data contact and convinced to upgrade, I then called in to cancel within 14 days in December and given another story, I then called in during 14 February and was told that I will be downgraded and after then only can I cancel but still has not been done, each time I call in I am given a run around with the staff and management no one gets back and they continue dropping the call and yet call are recorded what the hell is going on with Vodacom pathetic service
