Reliance Fresh — Deduction of double amount from my debit card

Address:

Ahmedabad, Gujarat

With due respect, I have made the purchase of RS. 643.50 on March 29, 2015, and once the debit card was swiped the amount was deducted but the transaction got cancelled. Once again the transaction was done and then it got accepted. I don't know what happened but the sales person told me that in 24 hours will be credited back to my account. THIS HAS NOT HAPPENED!! My 643.50 are due with reliance fresh I was frustrated as well as now worrying, as I have called them and got the update that they will be registering my complaint and within 7 days, I'll get my refund of 643.50 back. Hope that I get it... I have proof of the receipts as well as the messages that my bank have sent me containing your names in it.. This has happened for the first time in my life. Why they have this facility when it does not work??? I want answers as well as my money back. If you are listening please reply...
