Allahabad Bank — refund not issued to my bank account

Address:

Banaskantha, Gujarat, 385001

Acc name : sapan sunilkumar agrawal

I did 4 transaction on 31st march of rs 1011 each on bookmyshow which got cancelled and refund was issued to me of rs. 970 for each 4 transaction... But till date no refund has been credited into my bank account

I even contacted bookmyshow and they said refund was initiated on same very date but bank has not credited the same... Even in website it is showing that amount has been refunded but same is not credited by allahabad bank till date

Have wrote so my mails to them even called there customer care but no solution
