DSTV Price Lock - zero service & total mess with billing for more than 12months

Dstv Price lock has once again double debited by account for three months. Lodged an debit order that was not authorized nor signed by myself. Lodged a query a week ago. # ********** up to date have not received any communication nor feedback regarding this query. Attempts to call via your call center amounts to over 20 min on line before any call center agent answers the call - to even discuss a query takes 40 min plus on the phone = additional telephone charges with zero outcome - Not acceptable and continues ********** behavior without intervention from Management
