Good day<br> <br> I added a line to my existing contract with MTN, when receiving my new contract, 22.12.2015, I was promised 30 GB once off the next day. 2 days later i still hadn't received it. I then went back to the store. <br> I was told my package didn't come with the 30GB once off data, but I had a contract that was hand written and signed by the sales person who had helped me, I was then told the sales person that assisted me was not around and I had to come back on Monday 28.12.2015 so she can help me. <br> When I got to the store the Sales Person ( Percy) told me same thing that I was told, my package didn't include the 30 GB once off data. I said well its on my contract and you signed it. She agreed she signed it and still re iterated that I cant get it. I then said to her I will take it up , she then turned around rudely and told me I can take it up but I still wont wouldn't receive the 30GB once off data.<br> I doubt she realises that what is written on that contract is legally binding. She signed it and she still tells me I wont get the 30GB of data.<br> Does that then mean I can go back tomorrow to MTN and say I wont be paying my cellphone contract after I have signed a contract.<br>
