To whom so ever it may concern
My self saikiran did shopping on 6-7-2015 in one of the reliance trends - malaysian township - kphb 4 phase - hyderabad, purchased some goods sum of 2140/- . While billing through atm one of your employee at billing has swiped my card twice, in the first swipe no receipt has came out so he tried once again and i allowed him for it at that time i didn't received any message from my concerned bank, after one day i enquired my balance in the bank then i realized that my amount has been deducted twice from my account. I waited for three days thinking it may return to my bank account but it didn't, so i went to the store complained about the issue they verified my details and go through their receipts and said they have to concern their accounts section and can give further info to me. I waited for 1 week they called me and said we haven't received any amount twice so it may be returned your bank, so i went to the bank and update my passbook and that amount has not been refunded. My question is where is my amount i can submit all the proofs regarding my issuse. I want my money back please go all through the details and give justice to me.
Thanking you.

Saikiran.
