HDFC Bank — HDFC Bank - Transaction timed out

My name is Aniket Deshmukh.
Today I made a IMPS transaction from HDFC bank to SBI Bank.
The transaction says it's timed out.
The amount is debited from my account but it has not credited to the beneficiary account.
When reached out to beneficiary bank, they said the amount has not been credited and to contact HDFC Bank.
This is really not acceptable from HDFC bank, I tried reaching out to HDFC customer care, but I couldn't get connected even after trying for more than 1 hour.
I tried reaching out to my customer relationship manager, no response.
Is this your service? I'm customer of HDFC bank since 2015, now I might have to think of choosing other banks if this is the pathetic service.
