Reliance Jewels — Reliance Store not accepting old Reliance Jewellery due to stamp not being there

One Gold chhain bearing Tax Invoice number AXTR7019IN000568 was purchased on 02 Jun 2019 from Reliance Jewels shop in Dehradun. The chain broke so we came for repair at Reliance shop in Dwarka Sector 11 New Delhi. It was told that it can't be repaired. So we went for a new chain and decided to do exchange. However the bill given by Ddun shop was not accepted by the Delhi shop saying that there is no stamp on the bill. In addition Hallmark was not there at the correct place.
It is suggested that necessary redressal be conducted against my grievance. This creates not only lot of inconvenience but also bad name to the Company
