Vodacom order unfulfilled and lack of communication

Been a vodacom contract holder for about 8 years. Just started with a upgrade process to support them for another 3 years. I am not really price sensitive if it comes too service and I did not really shop around. I knew what I wanted. They offered me a new deal which just launched which I then accepted. One week later they inform me that the extra phone offered is no longer available and that I will not be able to get the deal.I already made arrangements with a colleague to sell the phone to him and give the watch to my wife. The only communication I got was that there is no deal I can just take the phone which I wanted. To make it worse, now after trying to contact the sales representative multiple times I am unable to reach him and he has no information for me. For the first time I shopped around, so looked at MTN. They gave me a contract for the same phone with more Data and Minutes monthly at a R400 cheaper price. That is without a deal or a onboarding process. I am just really disappointed in the service and how the whole process was handled with Vodacom. I went from a simple upgrade to now cancelling my contract and moving over to MTN. I really hope I do not regret this. But according to Surveys online MTN also wins in Customer Satisfaction....
