Hi.
Myself Rashmi. i had been to reliance mart kharadi, Pune on 18th may 2016. purchased some items and gone for billing. billing is done through my debit card. amount of Rs 1965 was deducted. den the billing person said billing reversal has happened so u need to pay the amount once again. initially i didn't agree. later he came with 2 more persons and convinced me to pay once again and the he said first transaction will be credited back to ur account within 48hrs if not come and collect cash from here. after 72hrs i went reliance mart again to enquire. but he said lik there is no update about that in his system.
what is this?????. its just cheating the customers. now 5 days over but there is no news about refund.and the person who spoke with me is also nt receiving my call.
i need my money back. i hav the sale reversal slip and bank statement.

thank u
