Vodacome Frustrating to deal with!!!:(

Vodacom "called me back " but of cause I missed the call. There was no number left for me to call back on and therefore I called the 082135 persistently but still had no luck speaking to any costumer services. I have now decided to change my service provider since I cant use a service when I can't even speak to someone when I need to and having to make numerous calls with no avail. They still had the audacity to send me a sms to say my query ha been closed! I am VERY frustrated can't deal. I have to say I never had issues with Vodacom before especially since I've been a costumer for more than 20 years with them and have always been able to call when I had issues which was hardly if at all.
