Premature Cancellation

I am not happy with the service I am receiving from vodacom cancellation department.On the 9th of this month I sent through a request for a premature cancellation ,a filled in form ,proof of payment and my ID copy basically all documents requested.I was advised it will be loaded within 48 hours .Two weeks later there’s still not a word from them . Every second day I need to take time off my business and follow up and every time Im being transferred,sent from pillar to post and I’m sick and tired .I spoke to a Lisa,Ntombifuthi the list is endless but no seems to know what their doing . As im writing this I spoke to a gentleman minutes (another follow up)ago and he promised me his supervisor Hlengiwe Khumalo will contact me whithin 5-10 minutes any 30 minutes later there’s no phone call from anyone .
