I am an account holder with savings ac [protected] at the vayu sena bhavan, new delhi branch, syndicate bank

On 20th march, 2020 i attempted twice to pay my mtnl bill via bank transfer but on both occasions, the transfer failed, however, my account has been debited with rs 263 on each occasion. Mtnl has not been credited by the amounts. The transaction reference is given below. The help desk advised me to wait for 5-6 working days but now it has been a long time.
