Demat — misguide

Respected sir,I am the holder of a/c no [protected] & my DP ID 12036000.I was misguided by yr representative MR. MEHUL JOSHI (Malad branch) to open a demat a/c instead of directly applying for a loan(commercial purpose).I was told that it would take 15 days for the loan to be cleared. I have given him 02 cheques for the opening of demat A/C(chq nos.1541405 &1541406 of amt Rs.2000/- & Rs. 750/- respectively& Rs.600/- cash).whenever contacted I was given a new excuse everytime.I came to know his intention only after I received yr welcome kit.since last week I have been trying to contact him but to no avail.Plz guide me in this matter & hope that some action will be taken at the earliest as I would like to get the amt refunded back to me that I paid towards opening of the loan A/C,the receipt of which was not given to me.hoping for a favourable reply.
