upgrade info incorrect causing additional chargesq

hi there<br> <br> <br> i have been calling you guys over and over for the last 2 weeks. i upgradred my contract and the info carried over is incorrect. you have charged me for an additional 5 gigs of data which was never supposed to be on the upgraded contract. i have been trying to get some sort of resolution to this as i am not willing to pay an additional R500... for something i never asked . its your mistake and i refuse to be the one liable for it. there are hundreds of call centre agents all of which just say things and never ever keep to them - nobody ever gives me any feedback and i am totally upset about this.<br> <br> i need this sorted out beofre my debit goes off on the 31st of this month. every single time you ask for a supervisor there is NEVER one available to help. how can you run a business like this?<br> <br> <br> <br> please call me urgently on ***/ ***.<br> <br> H.PILLAY
