cant even call it service because its that bad!!

<p>My contract was moved over from altech to mtn, this was don ein March. I srill have not recevied my airtime or data, Itumeleng Net****angani wa supposed to be assisting me but i get no feedback whatso ever? I got a mail from he ron the 6th of April saying that they needed to deactivate and activate my number to correct your package which was done. on the 8th she confirmed I'm back on contract but i still have no data or airtime and have had to buy prepaid. I've called mtn to try and speak to her manager with no luck and I'm tired of calling and calling and nothing changes? I'm way overdue for an upgrade and because of this I cant do that. my invoices dont seem to work either so I cant actually do anything!!! I am extremely frustrated. </p>
