Incorrect Billing

I'm so frustrated with this company, yesterday I checked my premium for the month of May it was R760.50. Then I checked this morning, and it was R1290.60 so I did the chat bot and it just infuriated me even more. They still bill me for something I don't have saying that I never paid a cancellation fee. I had that router for 2 days it never worked immediately I called and cancelled it. Now they want to bill me for ****. The amount I'm willing to pay was the amount of R697.70 and not a cent more. DSTV is like pirates they take and ***** everything they can. I want this issue resolved. That router needs to be removed from my name ASAP. And my billing needs to be rectified to 697.70. Not a day later then today. I have been a loyal subscriber for years, and I get this. I'm still nice and calm all I want is for this to be resolved so that i can connect my subscription
