Billing error

October I took the black Friday special for the price lock PVR decoder the price was 499, the package was installed I had extra view installed and had an existing showm showmax acco account with a discount, from October 2020, I have been paying R548 which is paid via debit order, this amount has been debited until july when I the price doubled, I called in first time and was told it would be rectified, and the di difference of R 548 woul would be transferred to me, I informed the agent that they can keep the extra amount as a credit to be collected for the premium that is supposed to go off on 26 August. Come august bill date my balance showed that i needed to pay R 842, which I sent a DM about and still has not been rectified to date instead the price I need to pay keeps changing from R 842 to R 1200 to R 225 to now R 465 and still no one is able to explain why I need to pay this, I have called in numerous times and your agents just put me on hold, the team leaders are not available and no one seems to be able to explain the additional charges. I did not add any new products. The only time I changed from compact to compact plus was part of the dstv Rewards where on the anniversary of when you opened the account you get upgraded for one month than it goes back to normal package. My only request is that you guys rectify the billing error and put my subscription back to the normal price of R 548 which i will pay as per normal via debit order, August there has been no payment because of the credit of R 548 from July's double deduction. I have had dstv for over 8 years and never had a billing problem. Please check statements from October 2020 and you will see that this has been my premium. I have complained on Twitter as well to no resolution. Customer number ***8
