Vodacom after sale customer care

The worst, I have been a customer for more then 10 years, I have more then one contract thats costing me a bundle. I upgrated recently and I wanted to use my old prepaid number on the contract been chating to contracts department and customer care with no luck. They queue to upgrade or give you a new contract but unless with aftermarket customer care. Had it with you and the bad service, maybe itis is time to change my service provider.
