Prepaid Reconnection

I have a bad Experience with their one2one service. I had a Sim contract with them which I didn't understand and their airtime was not working for me. So I decided to cancel it, I called them in September then they told me that they will cancel it in November 11th which they did. They advised me that it will take 24 to 48 hours for the reconnection .Then on the 15th of November decided to call them I was told that they are experiencing a technical error they even send me an E-mail saying that, since after that I have not received any correspondence from them till today. I want my Number back.
