Yupp Tv — Sony channels removed from ongoing yearly package - Refund needed

I have taken a yearly Marathi Silver subscription in Dec 2021 and it is a yearly subscription till Dec 2021. I paid in full for all Marathi & Hindi TV channels including Sony Entertainment channels, Sony Max, etc.
Suddenly from 1st July, they stopped listing the Sony channels without any consultation or call that this is happening.

I called Yupp TV for this issue, and they said that the Sony channels are not available anymore in your subscription and that you need to upgrade your package to watch Sony channels now. This means that for the same channel, I am now asked to pay extra for which I already paid before.

They ask me to pay 166.09 pounds over & above of what I have already paid for Annual Subscription...That's a complete harassments.

This is illegal and unethical, when you say contract it has to be followed both ways. I would want Sony channels in my package or cancel my subscription with refund. I do not wish to pay more for the same channels which are already in my contract.
