inappropriate billing

Hello de, My name is Nosipho M

I am very annoyed with Dstv, this month i upgraded from Dstv compact to premium on the 13th of February 2021, and i was told to pay R869 i did that, i normally pay my account on the 15th of every month... to my suprise today when i check my channels some are not showing, when i check on my profile i see i am downgraded back to compact n i didnt do that... day lite robery... now it shows i have to pay R806.. how is that possible? its not even a month n i have to pay again . i pay on the 15th of every month... i am very annoyed n disgusted by dstv
