I have noticed that my account is still being debited for a contract that is finished. When I contacted the Bluff store today, I was told that I need to call them and tell them I want the contract terminated. Now excuse my French because this is utter *******. They call you to ask if you want to upgrade you say NO, but instead of them ending the contract they put it on month to month. Now when you want to terminate you can only do so using a Vodacom sim or you need to go to the store to use their phone ??? I mean like seriously??? And all this was NEVER explained when the contract was taken or when they called to ask for the upgrade. Vodacom just found a loop hole to ***** their customers money. And in the two years I've had this contract I NEVER received a statement.
