Tata Sky — Tata sky stp not giving transmission

My tata sky sub. No.[protected]
Since morning ie.10.9.16 after switching on the tv the signal/transmission goes off within minute with a message on screen 'mode not supported". On conctacting over helpline i was suggested some steps (Which i did) but the problem remains. Then i was suggested engr. Visit for which i was asked to pay rs.200 which, in my vies, is wrong as the stp recently installed by the co. As per their policy, r not of good quality (As told by the co. Personnel doing the job).
Now i am asked to pay for no fault of mine. Moreover the person talking on helpline was rude/irritated without any provaction.

I request you to kindly look into the matter and get the problem redressed
Without putting any financial burden on me.
