Chamet Diamond Top-Up Paid But Not Received

I am writing about an issue I experienced today with Chamet regarding a diamond top up that I paid for but never received. I made a payment of 1000 Rs for diamonds on my Chamet account, where my user ID is 151297***. The amount of 1000 Rs was successfully deducted from my account, and I have a payment confirmation/transaction reference, but the diamonds were not added to my Chamet balance. I tried to reach Chamet customer support but I was unable to contact anyone or get any assistance about this missing top up. Since the payment has been taken but the service has not been provided, I feel unfairly treated. I kindly request that the missing diamonds corresponding to my 1000 Rs payment be credited to my Chamet account as soon as possible so that this issue can be resolved.
