Allahabad Bank — failed neft transaction but money debited from my account

Address:

Lucknow, Uttar Pradesh, 226003

I tried to do a neft transaction of rs 10000 which failed however later on money (Rs 10002) debited from my account. Previously also during one of my failed atm transaction money was debited from my account which did not get credit to my account and i had to lodge a complain to get my money. It came after 15 days. I have accounts in other banks also where if such a thing happens like failed transaction debit it is usually returned within a week. This bank has very poor service as compared to other banks in this regard. Kindly look into the matter.
