Malabar Gold & Diamonds — discoloration in gold bangles

We bought 2 baby gold bangles from malabar gold and diamonds - dubai karama outlet, last year (30.06.2018) for aed 1, 695/-. The bangles were gifted to our baby niece.

Over the last one year, the bangles have discolored around the edges to silver shades.

We visited the nearby malabar gold and diamonds - dubai qusais outlet to check on this. The guy at the qusais store, vineeth, claimed that the baby’s gold bangles may have come in contact with some harsh chemicals due to which the bangles have discolored. We tried telling him that our baby niece was wearing it and there is absolutely no way it has come in contact with any harsh chemicals! How can we trust 916 gold anymore?!!

On requesting to meet a supervisor, he said that nothing can be done. Also, he challenged us to go to court, rather than amicably resolving the issue. Extremely disappointed with the poor customer service.
