Ridiculous overdue amount that cannot be explained

I got the most ridiculous service today.Called dstv 4 times to find out why my services where disconnected.First call I spoke to Cindy was advised I’m overdue with an amount of R2840 I asked her to explain how it came about well no proper explanation was given till airtime ran out.Second person I spoke to was a guy called Mfundo I was advised the amount owing was R2000 he told me I was under paying from February 2019 I asked him to explain how it got to R2000 he could not till called disconnected.During the day I received an sms saying R795.33 is due on the account.My last call was with Happiness who was very rude she and the IVR advised me to pay R1045 the call was 54 Minutes long she kept putting me on hold because she has no supervisor “at that moment” apparently supervisors sit on a different floor than the agents which does not make sense, she then came back and told me that the supervisor she found for assistance says the only way they can resolve the issue is by me paying the R1045 that keeps on going up and down that wasn’t explained how it came to all those amounts and the reason why the services where kept on till today.??I was then told by Happiness that I must know the terms and conditions that I agreed to when I opened the account and I must stop asking how the amount came about.So the solution was I must activate debit order so that my account does not become in arrears but it was still not explained why services were running all along if I owe fluctuating and amounts on my account.When I make a payment either at a dstv agency or at their pay points I always ask how much do I have to pay for the month to avoid such *******.I then agreed to do the debit order because I need to have services connected.This time of the month I must pop out R1045 that was not budgeted for and I still have no closure as to how the account got be in arrears.All the people I spoke to today are *********** it’s hard to check the system they work on every day so they can assist me as a customer.Its clear that it’s a challenging system and the agents still need to be trained.I am not happy at all.Its enough that we are already paying for **** that plays on dstv now we have to experience issues that can’t be resolved like this.It sucks that I have to pay for something that was not explained to me the-rally for.Every month I pay for dstv but I have no right to receive a proper explanation.
