Khazana Jewellery — cheating while dealing with and receiving customer's old gold ornament

Address:

Dickensons road Bangaluru

My mother is a regular customer of khazana jewellers which is located at dickensons road. My mother had a gold necklace and a finger ring which was made by our family goldsmith. During my sister's engagement my mother planned to buy gold in exchange of her gold necklace nd finger ring at khazana. Before going to khazana we went to malabar gold shop and checked our gold purity and itz cost. Our necklace purity has come 87% and finger ring 84% which was matching with goldsmith data given to us. My mother was attracted by the collections in khazana so i went to khazana with my mother.in khazana we showed our necklace nd finger ring to floor manager who was a lady called ms. Deepa. S.
She took me to check purity of the necklace and finger ring to counter where one person was sitting for checking purity.
He checkd purity manually and estimated finger ring purity as 84% and necklace purity as 80% where as in malabar, for necklace it is 87%, on being askd wt is the proof will u give, he has no answer. We showed purity slip which was checkd in malabar. After seeing that floor manager has managed to increase purity of necklace up to 84%.
I started clearing my doubts regarding purity of gold by comparing with malabar slip.
Ms deepa said to us first to select any jewelleries and later she will provide us proper estimation. We selected 2 pairs of ear wears and final price was calculated. We askd ms. Deepa to get us proper purity of necklace at least up to 86% and we will pay extra 5k for those two ear wears in exchange of our 2 ornament. After a lot of discusion and bargaining she agreed for 5k and later she askd us to get heat treatment of necklace inside their shop. We got it heat treated and back to ms. Deepa when we were giving 5k she raised price from 5k to 5700rs.
I and my mother were very shocked, and we asked her we will give only 5k as per our deal. After geting it heat treated she began taking advantage and was not ready to take 5 k. We were shockd and hurt becz of her cunning behaviour. After arguing also she did not take 5k. Finally we gave full price came back to home.
This is how these khazana people cheat customer.
These khazana people are cheating educated people what if a common man with less knowledge about gold shopping come to their shop, he is finished in their hands.
Please be aware of these cunning peoples my dear brothers and sisters.
I request to concern authority to look after the issue.
Dnt provoke public to go consumer court.
