Despite 4 undertakings still await refund

I phoned *** on 14 August re an unknown debit on my DSTV account on 14/8 for R512-60. Was told error on their side as my Xtraview had been disconnected in error and charged as a separate Premium subscription. I was told reversal would be done in one hour. Nothing happened, phoned again in the afternoon, same story but still nothing. Phoned again on 15th (Mamello) and she too undertook to get the reversal done but again no action. Phoned yet again yesterday 17th, was put through to Xtraview department (Moosa I think) and he said reversal had taken place yesterday morning at 8:05 am. Well I went into DSTV website transaction history this morning and there is still no credit to my DSTV account. Evidently no one takes responsibility, follows-up and communicates.
