Tata Sky — Fiber OTT Plan is just 29 days

I get 4 OTT Apps thru my Tata Play fiber Internet connection.

However what I notice is that the Internet Plan is 30 days but OTT plan is just 29 days.
So OTT plan expires one day before the Internet plan.
When called customer care all they say is this is their policy.
However this is totally unfriendly policy.
Instead I would better buy individual services for one full year by paying fees directly to the OTT providers.
