Sick and tired of DStv billings drama!

Every few months it seems DStv does sum random audit on accounts which seems to result in a mess up. Yet again I have manual payments not allocated to my account or perhaps it is from the same nonsense from months ago when they could not decide if they lost a debit order in August 2015 or March 2016. I'm tired of sending MY PERSONAL BANKING STATEMENTS to people that I am just supposed to trust will sort out the issue.
