BDG Online Transfer Debited But Not Credited To Savings Account

I hold a savings account with your bank. On 25 November, I made an online transfer of 30,000 to this savings account. The amount has been debited from the sender account, and I also have the UTR for this transaction, but the money has still not been credited to my savings account. When I checked, I noticed that the deposit time shown in the transaction history and the time on my phone do not match, and despite this, the balance in my savings account has not increased. I contacted the bank, and I was told that the money has been debited, but I have not received any clear explanation as to where the amount is currently held or why it is not visible in my savings account. I request that my 30,000 be located and immediately deposited into my savings account without any further delay. I also ask for a clear written clarification of what went wrong with this transaction so that such an issue does not occur again.
