billed for contract that was supposed to be cancel

I phoned in to cancel my contract in January 2014 a few months after my mother asked why is she still being billed by altech as the the payments were coming off her account. I then told her it can't be I have cancelled that contract,I spoke to a consultant, I even got a reference number. Then May this year 2015 she tells me again altech deducted something like R700 off her account again,so I phoned headoffice again only for them to tell me my contarct was never cancelled. I requested for them to get the voice recording of the day I called as thet clearly advertise when you on hold that they record for quality purposes. I have been calling and calling for weeks now with no response from anyone,I get put on hold everytime I call and nobody takes the call. I have been waiting for them to tell me if I'm going to be refunded for the whole year and half that they have deducted fees and if they going to pull up the recording of the day I cancelled my contract. I need help with this please. I will never ever use or recommend altech autopage to anyone ever.
