Bad Customer Service

My query with Altech Autopage goes back to August 2015. I called the call centre and spoke to Girlie and Tumelo on the 04 August 2015 to have 2 of my DATA contracts cancelled, as both these Cell C sim cards never worked since I got them. I was advised to send an email which I did. to date I have not received and feed back! I have called many times to follow up and still nothing. I am still getting billed every month for something that does not work.<br> I find their service pathetic and will not recommend anyone to them!
