not saisfied with service

My mum signed up for a Telkom unlimited home 10mbps contract in March which included an intergrated sim with 2GB internet pm. After numerous complaints and visits to the Telkom in Gateway where an employee helped set up the sim it is still not active and we have been paying our account timeously. I would like this resolved and furthermore would like to know what will happen to all the months I did not receive my data as it was not my fault
