Ending cellphone contract and porting my number

Hello Peter<br> <br> I am going to tell you that Altech Autopage cellular provider is very bad. Last year in September 2014 I phoned customer services and I told them that I want to end my contract and go to prepaid, on the end of my contract, which ended on 28 December 2014. This did not happen after I tried to port my number to MTN. After that I phoned again and Altech Autopage customer services told me that I had to go another 3 months before I could port my number to MTN. Today the 2nd of April 2015 I tried to port my number again and it still did not work. I phoned again and asked why I can't port my number. So I asked them to revert me to prepaid and I am still not on prepaid after 28 December 2014. After speaking with customer services, they told me that I will have to do another 3 months on prepaid, before I can port my number. I asked to speak with the supervisor, which I was told that this person would phone me back and I got no phone call. After all this I think that they are telling lies and just wants more money and to rip you off with double charges. This company has literally cost me a small fortune to sort it out and a lot of stress with out compensation.
