IndiaFilings.com - I Feel Cheated Threatened

I don't know if these guys are genuine or fake, but their service sucks. I paid INR **** on Oct *th **** for a trademark application hearing (trademark application number *******), but never got the service that I paid for. I have followed up innumerable times but have either received no response or the customary "Let us check and get back to you". Check out this link to see my conversation with their so called lawyer : https://drive.google.com/file/d/*-*KLp-g*dSrqOqyHZ*BjeW-moMT*t*oT/view?usp=sharing When I decided to engage their services in October, a guy named Hayaz bombarded me with calls to make the payment. After payment was completed, there was just silence, no action. I have now asked them to issue a refund and posted a review on Google Play reflecting on my experience.
UPDATE: Their relationship manager has demanded that I remove my review otherwise they will not issue a refund. I don't trust these people at all (refer to my screenshot). I told them that my review will be withdrawn only after they issue a complete refund for failing to provide me the service that I paid for.
UPDATE: One of their executives had the temerity to call me and threaten me with legal action if I didn't withdraw my review. Can bullying get any worse? These people slept over the job, didn't answer my messages & emails. It has been more than three months since I have paid; despite that I haven't received an update on the status of my hearing (assuming that it has been scheduled; which I doubt) . When I demanded a refund, they made excuses. And now they have threatened me with legal action. My advise to anyone planning to engage IndiaFilings.com for any service is this: *. Please go through genuine reviews before you make a decision. *. Please think again about spending your hard earned money. Please speak to these people to see if they will offer your money back in case they don't get the job done.
