Multichoice lack of service

Changed to Explora package on 11/08. Billed R779 on 1/08, R849 on 11/08 and R718.34 on 1/09. Called on 2/09 @ 08:48 (Thembelihle) to find out why and was told that they had not stopped Premium account and started DPP account. Told it would be escalated to accounts to rectify. Followed up on 3/09 @13:20 (Dikiledi) told the same thing, escalated to accounts. Followed up on 8/09 @14:05 (Dikiledi) told the same thing AGAIN and promised to call me back with feedback, never happened. Followed up on 16/09 @12:15 (Thabo) told the same thing AGAIN and promised to call me back with feedback, never happened. Assured I was in credit and debit order on 1/10 would be R199.06, debit order ran last night, Multichoice took R899.67. Called today 2/10 @ 9:45 (Sendiwe and Itumeleng) told they would escalate to accounts for the FIFTH time. I am so frustrated with the lack of customer service and really don't know what else I could possibly do get Multichoice to fix this. Perhaps if I go to their offices and refuse to leave till they sort this out they might assist me?
