XM Missing Deposit Issue

I deposited 8,199.66 INR into my XM trading account number 91958*** on 30 June 2026 at 01:24 pm via Amazon Pay UPI. The amount was successfully debited from my bank account and the UPI transaction ID is 618177593100. However, XM is denying that the payment was received on their side. After noticing that the funds were not reflected in my trading account, I immediately contacted my bank and raised a Chargeback Recall Request. This request was later rejected by the beneficiary bank, confirming that the payment had been successfully processed to XM. I also obtained an official letter from my bank clearly stating that the transaction was completed successfully, and I have shared this and all other available evidence with XM support repeatedly by email and through their support channels. Despite this, my issue has remained unresolved for nearly two months. The funds are missing, XM keeps claiming they did not receive the payment, and support is no longer providing any concrete response or solution. I request that XM urgently investigates this transaction and either credits the full amount of 8,199.66 INR to my trading account or immediately refunds it back to my bank account. I also expect a clear written explanation of what went wrong with this deposit and why this issue has been left unresolved for such a long time.
