Disappointing service from Mytfgconnect

Im soooo unhappy and frustrated with mytfg connect, after being offered their contract and porting of my number to mtn, their sim was delivered on monday and i called them on tuesday to cancel the contract. I was told i would have to wait because the porting was already in progress and if it succeeds i would have to use the new sim card. My number was ported to MTN but now the sim card is not working. I had to call MTN to check and was told its because the sim was not ricad, i tried to rica the sim but no store would assist, MTN could also not assist with porting my number back because according to their system i still have a contract with mytfg. I called mytfg just now to follow up on the cancellation n was told that on their side my sim had not been ported yet the contract has not been activated and so i would have to wait until they get communication from MTN before they can cancel the contract on their side. So now im stuck with my old number that has been ported and a new sim card thats not working, i was told they would communicated within 24 to 48 hours, with both numbers being inactive since Wednesday night , im being told to wait till next tuesday for an update. Totally unacceptable , one of my biggest regrets and i wold not recommend this service, it has brought me a lot of frustration and being told that theres nothing they can do, their system doesnt allow this and that...Very disappointed and upset!
