Worst service ever

I want to pay my account, only to find that I am being charged a ridiculous amount which doesn’t make any sense. For the month of May, I paid R709 which includes Dstv package, Showmax and the Dstv WiFi(internet). Today, which is the 30th of June, I now suddenly have to pay R1108. When I request a June statement, there’s nothing, only May. And they will charge me for paying a day late when I have been dealing with their chat agent Thandokazi who was not helpful at all
