No service delivery

Good day On the 6th of January 2022 my son rented a movie for his birthday, I agreed of course... Lol. However we never received the movie... Movie name is OLD. We whattsapp, email even tried Facebook but nothing, not a word from DSTV. When I called to report this after realizing that I was charged for the movie end of January, i called dstv and the guy that's supposed to help me told me he can't help without the voucher no...... This is after giving my ID no, date of rental, title of movie n customer number he he merely said without the voucher no there's nothing he can do for me. Then why ask all that info in the first place. Then we are asked to support local business but yet dstv can't assist regarding how you make contact. On Friday we had a terrible storm n since then I can't watch TV.... Only recordings still they can't help me.... What now?????
