Service cancelled 16 Jan and still being billed.

I cancelled my ADSL and telephone services on 16 Jan 2015.<br> <br> I was told that it takes a month for the cancellation to take effect and was given the date of 16 Feb for it to be effective. Sure enough, they stopped my ADSL service and disconnected my phone line, yet they are still billing me each month.<br> <br> I have no Telkom phone line anymore, so cannot contact them on 10210. I have emailed as suggested by the automated system, but this has not yet received a reply.<br> <br> I am due to be refunded 2 months of service fee's and my R700 router deposit. I also expect Telkom to stop billing me for services that I am not receiving!
