Contract Cancelled Still Being Billed

I cancelled my contract on 02-06-2015. You are still debiting my account. The service I received was horrible. I am struggling to get through to your call center. I need the money refunded which you are deducting from my account. I actually need to be refunded all the money that I paid to NEOTEL this far as I have had NO signal on my device for 6 months. NEOTEL could not resolve the issue and I don't see how I could have paid for something I was not getting.<br> <br> MY MDN number ***<br> <br>
