ItzEazy.com — HP deletion work

Hi, I had given an amount of ₹3000 for HP deletion services in the month of March 2021, after several follow ups since we then, in end of June 2021, someone named Mitali mentioned that my amount would be refunded soon.. it’s 20th July 2021, I’m still following up and today on calling their customer care their call centre representative asked me to
Wait for refund.. without specifying the no of days for it ?

Very very unprofessional company, can somebody help me to file a formal complaint on this company
