Cancelled account billed

Good morning,<br> <br> I went to the branch a month ago to ask for my tablet contract to be closed or converted to prepaid and I was billed again with an even inflated price without discounts.<br> <br> I can't get hold of the branch or the 180 service. I hold until I get dropped.<br> <br> I have even gone on the site and have asked to be contacted.<br> <br> I have even email a consultant from the store.<br> <br> No help.<br>
