Tanishq — Cheating during Gold exchange at Tanishq Cross Cut Road Coimbatore Branch

Address:	Tanishq Cross cut road branch
Website:	Tanishq.co.in

I was at Tanishq Cross Cut Road Coimbatore branch to sell my Tanishq jewelry which I bought about 2 years ago - 1 chain (11.956 grams), one pendant (1.655 grams) and one finger ring (1.617 grams) - total value of the gold was around Rs. 80, 000 as on that date.
I also bought 2 pairs of earrings in of value Rs. 36, 079 and I requested the remaining amount to be refunded into my bank account.
The sales person agreed and took it to the counter for processing.
At the counter, the person processing the bill and operating the system agreed that the old jewelry were all Tanishq jewels. He mentioned that because there is a purchase also, the system cannot process the (Old Gold - New Gold) refund directly and that he had to cut the chain to match the purchase value and the refund value. I found that to be rather odd, but thought it was Tanishq's system limitation to process it.
I asked for the refund value and I gave my cancelled cheque to process the refund.
in the purchase part of the cut chain, he said there was a little more and refunded me Rs. 147 in cash. When I asked for the refund amount for the gold, he mentioned that it will be automatically processed in the system and will be refunded within 7 working days.
It was closing time. They were pulling the shop shutters down. I again asked for the exact refund amount. He said that it is all in the statement and put the bills in a Tanishq envelop and distracted me with requests to invest in Gold savings scheme and such talk.
Now, after 20 days, the amount for my gold has not been refunded into my bank account. When I look for the statement of refund amount in the envelope, it is not there. I am clearly cheated.
Please please help me get back my refund amount. I wanted to sell the jewelry because I needed money and it is not available to me now.
I have been a customer of Tanishq since its inception over 25 years ago and it is my favourite jewelry brand and I did not expect to be cheated here in this manner.
Every jewel I buy is a story for me and every jewel I give in exchange has a history and it Pains me so much that I am cheated at the place I trust very much.
Please Please help me recover my money. It is my hard earned money and I needed it in time for a reason. Please Help.
