biiled for months after I didn't renew my contract

I've had a contract with Autopage since 2010.I was supposed to renew my contract last year but made made it very clear to the guy I spoke with that I wouldn't as I was not happy with their service.To my shock,an amount of over R600 was debit from my account.It then happened again in over and every other month thereafter!I've called them several times but get sent from pillar to post with no positive outcome.I called them again on the 6th/june to resolve the matter and was told the recordings of my call made on the 21Oct14 when I said I wouldn't be renewing wuld be listened to but nothing was done!Then on the 8june15 my line got suspended!Frustrated,I called them and related my story to a lady named Lebo who is in the retentions dept,who later hung up on me without assisting me.I called a few times after but got cut off with every attempt.A few hours later,an indian guy named Joe from head office called and promised me that my line would me reinstated and that I would be refunded all my money.Needless to say,7 days later,my line is still suspended and I've had no feedback from them!They are all imcompetent and don't care about their customers!
