Got Disconnected, Again!!!

I received a call on Tuesday from a call centre agent saying i owe Autopage R200. I asked her where the R200 was coming from since i have a contract with Autopage for R399 per month and the money is taken via DEBIT Order each month and i saw confirmation of payment via sms to me. She said she was going to investigate and call me back. Soon as she dropped a call I received an sms saying I owe R200 and must pay immediately or get disconnected!!!, mind you i have my April invoice which shows that I paid in March all dues and no mention of any brought forward balance of R200 anywhere!!! <br> <br> Yesterday, I got disconnected!!! I have no idea where the money Autopage is demanding me to pay is cooming from. All my invoices show that I paid all your dues , besides, all transactions happen via Debit Order so I do not understand how i could owe you guys any money. This is really bully behaviour which is totally unacceptable. Two months ago i was diconnected again for 16 days over your fault!!!<br> <br> I regret why Nashua Mobile closed down. I was a very happy Nashua Mobile customer and from the month we got moved to Autopage, I have had no joy! Every month there is a mess up. Please fix this!!
