I am so disappointed in Vodacom. This is the third month in a row I HAVE CANCELLED MY CONTRACT. I have cancelled my contract with vodacom and asked them to please make my number prepaid. I have stood in ques for hours just for them to tell me I have to phone in and cancel...Guess what i did phone not once not twice many times I spoke to Tobi on the App and I have spoken to i cant remember how many People. I give a message call a recorded please check back and see how many time i have phoned in....... Ref number ***. I have been a client with vodacom since 2004 why is the service so BAD........
