Airtel — wantedly making delay in channel selected by me and deduction of recharged amount

Address:

Namakkal, Tamil Nadu, 637303

I have got new dth connection from your company in december 2019 @ subscription amount around 790.00 per month. As per new rules i selected a pack as my choice for rs 377.00. Permonth. I recharged 900.00 for my account as two months subscription. But till date rs 600.00 only in my account. They take around 300.00 without my concurrence..
As per your advice i picked my my plan from 1 at feb. But till date my plan was not changed and they cheated me.
Kindly do the need full or otherwise i decided to disconnect
Waiting for your reply.
