Airtel — not able to view channels due to blurry vision

Address:

Mumbai City, Maharashtra

I'am not able to view channels due to blurry vision. It gets blurred in between and is very disturbing to view. I have tried other methods also like re-inserting the card again but still there's no improvement. I request to resolve this issue as soon as possible. There is not even a single channel which can be properly watched.
Please solve this matter as soon as possible
