MyICICI SAVING BANK ACCOUNT NO is[protected] & Debit card no [protected].
On 10th December I purchased Petrol of Rs.400/from Modern service station HP DEALER, IT COLLEGE Crossing Lucknow. I made payment through debit card but dealer swapping m/c was not working properly therefore I could make successful pyament on third attempt. Lateron I found that money was debited from a/ c THREE TIMES( ie 400+400+400) while I could get petrol of Rs/ 400 worth only.( pertaing screen shot is being attached for your persual)
Again on 16th December I have again purchased petorl from same dealer for Rs. 400/ and made payment through same Debit card but this time again swapping m/c did not response but Rs. 400/ were debited again . ( pertaing screen shot is being attached for your persual)
Ultimately I have to make cash pyment.
I, immediately personally contacted the Manager of Petrol pump but he told that money has been credited in his account( 400+400+400=1200).
