not wanting to refund my account

I requested that my DSTV be cut off on the 15 as my billing month runs from the 15th of a month. I phoned on the 13th as was cut off by the end of the call. I enquired about my stop order and was advised if the run was done I must phone and DSTV would just refund me or go to my bank and have the stop order reversed. this is at my expense. on phoning today to have the money paid back I must provide bank statements after the conversation confirmed my payment had been received on the 15th. I only get a bank statement with this payment next month. I want my money refunded within 7 days as advised. they were quick enough to cut me off but to request a refund it a timeous process. totally unacceptable. this company has no integrity
