Let us make a move with letters and file a complaint at condumerforum..

The company takes more than a month just to prepare an application to file. I had requested trademark registration in the month of July and till now they haven't filed the same. The representatives will be busy most of the time hence unable to talk to them. People on reception who take the first call are usually arrogant. Their telephone lines are not stable and will drop frequently.
I never suggest taking any services from them.

File a police complaint and a complaint with MCA ICAI and https://sfio.nic.in/

You will have to pay 3000 but seek costs and damages from them - if enough people act, we can put such organized frauds out of business. I have had enough undue stress because of them. No more..
