Refusal to provide the service paid for

Against my better judgement I recently allowed myself to be convinced to move from Vodacom after 12years to Telkom Mobile. I have really started to regret this move already. I took out an unlimited lite package which is advertised in both your brochures, in store posters, flashing screen adverti*****ts and website to included 1GB of data per month. However, when I tried to use it, I got a message to say I am out of bundle. Trying to get through to the call centre proved to be a nightmare. The amazing thing is that whilst this promotion has been running for at least two month only 1 of 14 people I have engaged with, knew of the additional 1GB. Two cases have been opened and closed without being resolved. The matter has also been \escalated"without being resolved. The store manager where I took the package at Fairways Crossing"
