Incorrect subtitles and poor customer service

I informed Showmax that their subtitles on the show 30 Rock is incorrect.

What appears in the subtiltles sounds like what is being said, but the words are entirely incorrect.

For example; Season 3, Episode 10 around 8:30

The character says: "Buster, come here boy!"

The subtitles say: "Pasteur nearby"

They sound simi****, but the subtitles are complete nonsense.

Showmax's reply to me was to inform me that the subtitles on their side is correct and I need to restart my TV. When I informed them that this has been an ongoing issue for weeks that I've watched the show, their response was to ask me what show I'm referring to as if I did not identify the show in my initial complaint, and they already told me the subtitles on that show is incorrect.

Luckily I'm only hard of hearing and rely on the subtitles for clarification, but I cannot imagine that a deaf person who relies on the subtitles to know what's going on is able to watch the show.

So does Showmax simply not care about their hard of hearing communities? And is it common practice to lie to someone before even checking if their complaint actually has merit?

Utterly disgusting service.
