DStv again

Again, DStv is stalling the cancellation of my internet package. After the 3rd time round, I've been told once again that I will get a call back regarding the fees I would need to pay, I don't even now i the package has been cancelled as I have not received feed back.

I have a debit order on my account for my monthly subscription, If I get paid early I would normally make an early payment to dstv using the online method, I would check once done or a day later to see if my account would be updated and without a doubt its updated as soon as I make payment. For the past two months I made early payments but have been charged twice for a reversal debit order. I don't understand why a debit order would be going off my account when I've already made the payments.

March - R82 and R68 Feb - R112 and R92

Could I get verification on what the heck is happening on my account.
