DSTV not delivering on what they say and slow to respond

DSTV channel 166 displays a message on the screen for the full duration of the programme "Hindi Audio Available To access, please select the alternative audio track"

When selecting the alternative audio track, it does not provide the Hindi audio.

I contacted DSTV live chat and spoke to Sia. Sia advised to send an email to ***

I sent an email to ***

All this does not help me to watch the movie in Hindi right now.

DSTV, please do what you say. Why do you keep the message on the screen for the full duration of the movie but do not make that advertised option available?
