Mp Jewellers — defective product and refund

Address: Dibrugarh, Dibrugarh, Assam, 786001

My mother had bought a golden ayesto (Bangle) on 25th october, 2019 on dhanteres from your showroom in dibrugarh, assam. It broke off as manufacturing was not upto mark and then they fixed it. Again it broke off in january and now they have again told me that they will repair it. I am asking them for a complete refund but they are saying that they wont refund the labour charges. I feel cheated as a customer as i have had to face harassment twice over the same issue. The quality of the product and services hasn't been upto the mark. Kindly provide me the full refund in exchange of the product.
