[Resolved]  Sify Broadband — cheating case

i am using the sify broadband service since 6 months & my plan is 1550 family pack in that plan i get a 150 mb in day time i.e. (from 8.00 am to 10.00pm ) & unlimited downloading in night time i.e. (after10.00pm to 8.00am)

but now what happen to me i will be charge even for night downloading. when i call in customer care i told them about my problem they said to me "we will look into the matter & it will be resolved within 4 to 8 hours " but after 12 hours when i called again in customer care so nobody respond positively they said "your complain is in the progress"

what should I do? I am totally fed up with these . so i want compensation regarding my problem & I need my validity 30 days more and need strong action against the concerned persons.
