Reliance Jewels — Fraudulent billing at Reliance jewels punjagutta

I've purchased a gold ornament on[protected]. Total outstanding amount was 295000.00. 100% exchange within 7days. Due to size incompatibility I've to exchange the ornament on[protected]. The latest ornament weighs 0.38 grams more than older one, effective gold price would be roughly Rs.1900 (0.38× 4781), but I had to pay Rs. 8400 difference amount to get new ornament. It was illogical to think about the bill. Manager gave me unsatisfied and unconvincing reply. I can add more details based on necessities. I seek your attention to look into the matters and do the needful.
