Utterly bad customer service

What utterly disgusting and most disappointing service we got from Vodacom (both their call centre as well as their store in Tygervalley) We run a business and enquired about a change on our managing director’s contract which, before doing so, they confirmed was possible. We went ahead with it and they consequently decided to do their own thing, not at ALL what we requested!!!! This resulted in my director now having a different number and none of our clients can get hold of him, as his previous number has been known by our clients for many years and also branded on all our company vehicles, his cell phone number being the main contact. NOW after all this, Vodacom advised us that what they told us previously was possible, has now become impossible!!! Perhaps not all employees at Vodacom receives the same training? Their incompetence is now causing our company a lot of money and inconvenience and doing a lot of damage to our reputation, causing us to lose a lot of business as no one can get through to the number advertised on our vehicle…. You can imagine how unprofessional this looks on our part. We have been on the phone with them numerous times as well as wasting our time going to their store also NUMEROUS times! None of the promises made to us has realised thus far and now they want to take it back to the way it was, but that they are also finding hard to do. Now we were informed that this will take a week to sort out!!! Completely unacceptable and most definitely grounds for cancelling this contract seeing as surely this constitutes contract breach on Vodacom’s behalf? As they all have a different story, we have absolutely no idea where we stand with them now or what to believe?? We had enough!!! Either they cancel this contract so my director can port his number to a different competent service provider so that we can get his number back and trading again, or we are quite prepared to approach our attorney to take this matter legal and sue Vodacom for loss of income, since this have been going on for more than 4 days now. We are done with this back and forth now, and if a satisfactory outcome is not reached today, we are taking this further!!
