Appauling service from Vodacom

Did a telephonic upgrade with vodacom and cancelled within 14 days as I found a better contract with vodacom that was value for money if I walk in. Found out after 14 days that the contract is still in place and vodacom states there was no request for cancellation yet when I phone 1950 the consultant states cancellation was logged 4 days after the upgrade was taken. It is now a nightmare dealing with vodacom and if I take the issue to a vodacom shop they state they cannot help me as I need to phone in. No one can help me at vodacom despite numerous request. They state they now need to quote me on a premature cancellation. Service vodacom has been appauling. The level of s****, customer service and interaction was of a very poor and unprofessional level when dealing with the consultants telephonically.
