Complaint regarding refund from idaynt company

I invested 3540 in idaynt company to get interior leads. I paid on their trust that they are not a fraud company but after 4 months also the company was not capable for providing me the lead. When I asked for the refund they promised me that they will refund but then they avoided me didn’t pick my calls and never refunded my hard earned money when I complained on the customer support they asked me to download a file over the call but the file was a spam file and they kept saying that it’s a refund process. I’m scared to invest in any company now. I would like to get a positive response after the complain and would like to get a refund as well.
