Simswop

Please help. I am getting no help from MTN Menlyn branch. They have two branches but this does not help. The ground floor branch does not have sim card always and the lower ground floor make you wait forever and tell you after a long wait that they are offline. On Friday I insisted at the lower ground branch to be helped and Nelly was just pure rude and there was this guy who told me to call 808 and they can assist me over the phone. Today I called 808 and was assisted by Andrew Crouch, who did not even listen to what I was saying. He insisted I go back to the branch and it is just not working for me. <br> I don't want anything else, all I need is to get a simswop. if this was my number I would cancel the contract and open a new one with different service provider, now it is for my mom, she is not ready to change to any service provider. please help.
