Punjab National Bank [PNB] — transaction failed still amount deducted

Address:

New Delhi, Delhi, 110095

Pnb customer with complaint sr no. A[protected],
I debited rs 7000 from vijaya bank atm on saturday around 11:40am, received text that amount has been debited but on machine display its showing transaction failed and i did not received any amount.
I contacted with your customer executives many times and from last 4 days they have only one answer that my complain is still in process. See take your so called 7 working days or more to refund that amount but i want a reply that yes via machine i did not received any amount so i will receive that amount by you people as its your mistake.
Please look into the matter at the earliest.
