Vodacom Dropped Calls

The amount of dropped calls I have been experiencing over the last few months (about 4 months) is truly unacceptable. It was about 1 a day, I would say, for the last few months, but over the last few days it is EVERY SINGLE CALL!!! I once received "compensation" for my dropped calls. An SMS saying I received 10 free Vodacom to Vodacom minutes. What a pathetic excuse for compensation for an extremely frustrating inconvenience! This kind of service is completely unacceptable!
