DSTV ******* and false amounts

In April my bill came to R1800 and it was debited from my account, I paid the amount, contacted DSTV to investigate and was told they would phone me back, to date no one called, last month my account was normal, now I am told I must pay R2554.84 for the month of June, how is this possible, I have a contract of just under R900 and my holiday home was switched on for 3 days on the DSTV app, I accepted the contract of R75 for those 3 days, now when I call the lady tells me that I must pay the holiday home for the days from 1 June till now, I never accepted any contract for that, What is going on with my account, it is an impossible amount, *******. I am going to cancel this account if it is not sorted, streeming is cheaper.
