MTN are dishonest and ***********

I purchased a second cheap phone about a month ago with SIM share facility on the understanding that if my main phone was switched off it would auto divert my calls to my second phone. A month later and over a dozen phone calls, 4 visits to 2 stores with a 30 minute wait each time and my calls are still not being diverted. I went to Canal Walk store yesterday and was told that this problem would be fixed within 24 hours and that I would receive an email to confirm this. Neither the problem has been fixed nor the email received. I have now phoned up the help line and was told that she would send a follow up email to the technical team to get back to me. I requested the technical teams number but was told she couldn't give it to me. She refused to put me through to a manager so I could escalate the issue. It appears that the technical team are either imaginary or *********** as they cannot fix a simple problem. The customer service team are also completely dishonest as no one ever gets back to me to resolve my problem. When I state that if they cannot fix the problem I will return the phone for a refund they say there is nothing wrong with the phone, so bad luck suckered.
