Unhappy customer!!!!

Iam an unhappy loyal customer to the cell c. Been with them for more than 4years.would have moved to another service provider but due to time & the work iam doing time is not on my side hence iam still with them. I bought voice bundles twice thinking I had done a mistake with my initial puechase since I have not received a confirmation sms but it was confirmed by the consultant that the purchase was made but Calls I made later were deducted from my airtime still. The lady(phindile) is very rude, lacks ethics, customer care is not her strong point she just told me iam not the only one the problem is being fixed & just transferred my call to the machine.
