Bad service

My lady took out a contract for me at telkom (cradlestone branch ) that I'm paying she told the guy to put the spend limit on 0 and to port from Vodacom to telkom ,but he didn't do it and now I used almost R300 of the spend limit which I didn't know is still active and i don't have the money to pay it ....he confirmed that it was set on 0 and that the number has been ported but nothing that he said he done was ever done ....he didn't even capture details when she when to edgars to check the account she had to fill certain things in again, I'm not even a week with telkom and I'm already starting to regret the service I'm receiving
