Non existant customer service

I have been a loyal Vodacom customer for over 15 years and have numerous contracts. At end of July I called to do various changes, etc. to my contracts. After having to follow up on several occasions and speaking to at least 7 different people. It is now 19 September and have still received no joy. I find that there is no customer care or service. I have decided that as my remaining contracts come to an end, I will rather cancel them and go to a service provider that values there customers and treats them with the respect they deserve.
