Debit order dog show

In July we upgraded from the HD PVR to an Explorer linked to my Dual View. Our monthly debit order for the last 2 years was approx. R779.00. At the end of July we were debited an amount of R1921. When I called to query, the lady I spoke to admitted that they have continued to bill me for the disconnected HD PVR. I was due a credit of approx. R1000, but surprise surprise they weren't actually going to refund me but credit my account. <br> End of August and not only didn't receive this credit, but was debited another R1558. I called in to the call centre on Sat the 5th and spoke to someone who informed me that it would seem that none of my previous queries had been actioned, I was asked if I mind holding while she check on something and was then put on hold for 34 mins, so had to cut the call. I called again later went through the whole explanation again and was again put on hold for 30 mins so again had to cut the call. Today I finally get hold of someone who tells me a credit will take over 40 days as per policy and she cant find a trace of my first call. They take your money don't resolve your queries and provide a ridiculous service. Please don't allow Debit orders with this org.
