Trai — monthly dth cable operators charges by hathway

Sir,
Our dth cable provider collected rs.250 per month till last month saying that it is post paid.
Infact, he was collecting rs 200 or 225 pm earlier on post paid basis.
While enhancing the monthly charges to rs 250/- he said we have to pay in advance and collected rs. 250 as prepaid. But now, since last month, he has been claiming that it is post paid and collecting charges.in the process, we have ended up paying one prepaid and one post paid charge for the last month.
Now, again, with new trai rules, he has again come to collect "a-la-carte" charges as prepaid minimum rs 300 plus.
Is it mandatory for us to pay base pack charges of rs.153/- in advance?
He has not been giving us even the free to air channels since 5th of this month.
Whether he is right? Are we supposed to pay for the entire month though we have been without connection for the past more than 15 days.?
Please clarify immediately, sir.
