Unhappy customer

Hi, Dstv is double billing me. Please help me found out how much exactly am I paying for my subscription each month because it seems like dstv is billing me twice. I've send the help desk emails regarding this complaint but still no word from the agent . I even have the reference numbers for my complaint :Ref ***4 and ***0. I was told to pay 314.27 before the 25/05/22 and now they say I must pay 497.98 on the 07/06 /22 . I am not very happy with the service and I really need to know how much exactly am I paying each month because I wont be billed twice. last month I was told to pay 1001.10 not even sure how it even came to that amount but later told the was a mistake and I must pay 679.00 so please I'm asking the agent to call me on *** to rectify this error.
