No customer service

Yet another complaint about vodacom with regards to a upgrade. 3 days after upgrade was done over 48hrs continued calls to call center over 3 days been told more then 5 times someone will be in contact to get upgrade confirmed and here we are again no phone call back to get uograde confirmed no feedback no help and 2 complaints later still nothing so here is now the third complaint and very very poor customer service we are ready to cancel all contracts and move to a new service provider that can offer better customer service to their clients and that make sure not to lose clients
