NO INTERNET FOR 12 DAYS - APPALLING SERVICE

I was the unfortunate victim of theft but was luckily covered by MTN insurance. I went to the MTN store in Tokai on May the 16th 2015 where I received a new phone and sim card. For two days (16th +17th) everything was working perfectly. On Monday the 18th, my signal disappeared and I had no service for 6 days. I called the helpline several times with no luck and in the end, the manager from MTN Tokai helped me out. After 6 days my service came back on but on the 22nd of May my internet dropped out. I have had no internet for 12 days and I have been in constant contact with MTN employees who claim that there is nothing they can do. I have also called the helpline several times but each time a recording tells me that it is not functional. I have been to several stores and again, there is nothing that MTN can do. I have even requested to change my number or cancel my contract and was told that this is not possible. I have lost several clients from my business because of MTN's incapability to rectify the situation. MTN IS *****ING MY MONEY!! WORST NETWORK IN SA! DO NOT TAKE A CONTRACT WITH THEM - YOU WILL REGRET IT!!
