MTN airtime balance glitch!!

I have moved my primary number from Cell C to MTN in hope for a better service - was I wrong! For the past few weeks every time browse the Internet, an out of airtime notice pops up and informs me that I have no data or airtime left. When I check my balance, it shows that I do have data and airtime, but I can't access the Internet, thanks to an MTN airtime balance glitch.<br> <br> My airtime also mysteriously dissapears, within a day of recharging, when I make a decision to purchase bundles it states I have insufficient funds despite having enough airtime in my account. This is absolutely unacceptable and forces me to browse at out of bundle rates which is costing me at extravagant rates! This is a MAJOR inconvenience and Frustrating!! MTN head office, you have lost my trust, if this is not reversed you will losee a client for LIFE!
