Vodacom's lack of customer care and poor service provision

My boyfriend went to open up a contract with Vodacom, switching from MTN because of their bad customer services for the past few years. So far Vodacom haven't been any better. There was an incorrect credit check done and when we sent a letter as proof of this, they have not bothered to reverse or override this on their system in order for us to open a contract. They have never contacted us with updates, we have always had to phone them. Clearly they don't want new business nor do they care about customer care.
