Unacceptable and delayed customer service

I have a service request number a6-wwexf-gh17k. New service request number S3-85L18-849P3 outstanding for almost 3 months still in a pending status. I have spoken to a total of 15 consultants that incl team leaders, managers all who make promises and never revert back to me with feedback. My voluntary call limit cant be activated for me to control my cost that comes to almost R3000 a month. this incompetency is costing me a fortune. I am not getting the service I expect. Nobody at Vodacom is taking accountability or resolution. I call every month endless to activate my call limit and every time I'm told that there is error on the system. My contract is up for renewal on the 4 July. I cant wait for my contract to end so that i can move to a different service provider. The customer service at Vodacom is shocking, the turn around time for resolving requests are unacceptable 3 months. I am a very unhappy customer and feel vodacom exploit customers with claiming system errors.<br>
