Atrocious service, wrong charges and no answer!

Vodacom your service is absolutely ridiculously disgusting. We just received a bill of R649 for a u choose flexi 110...how is that possible? !? First of all we get approved for a bond over 1.7 million yet when we moved companies and had to put the contract on our name you downgrade us to that ****pie plan...apparently you're investigating this yet nobody is getting back to us... This plan is capped that when we run out of airtime you cannot deduct more airtime and now we get this bill?! And now we've been on hold for 16 minutes and still no answer. Your service is atrocious. I suppose it's time to leave your terrible service and move to Mtn or Cell C!!!!
