one2one BAD SERVICE!

Bad Service, I cancelled my contract with one2one because I had a data only contract with them, only to find out that they were also charging me more on calls, more then R2 a minute. I cancelled my contract and was told i had to wait 30 days for the cancellation. After that 30 days one2one switched off my cell service, I then tried to port back to MTN but MTN says they can not touch my number as it is under one2one, I called one2one countless times and their call center does not answer my calls, I sent them emails and not a single reply from them. My number is not working for 10 days now and everything of mine is linked to that number.
