Home Internet Starter Monthly contract Horror experience with MTN

I have Home Internet Starter Monthly contract with MTN that allows changing location in 12 month, i have been calling the since Sunday to change my location as i currently moved to Guteng. Lihle ,Aneliswa,Sindisiwe and many more agent said i don't have coverage where i stay i must return the Router to MTN store for cancellation. Funny enough when i go through MTN website and punch my address it shows the is civerage and is giving me option to apply for a new contract.

If the information on the MTN website said i have coverage and can apply for a new contract, why must i cancel the one i have and apply the same thing. They must just change the location and let me dead with the consequesnces.

One agent Lihle on the 2nd of Feb said she was going to send email to the supervisor so that they call me back , it is no past 10 i still haven't received a call from them. At 10:00 i spoke to Aneliswa as a returned call because i was running out of artime but during the convesation she went silent on me and i was left talking alone it seems like their network is poor.

Please get me a Team leader or manager to urgently call me because as is, i have spent more that 200 in data for daily us and airtime to call and no one is bothered to escalate the query to the next leved. ***
