Mcdonald's India — order cancelled money not yet refunded

Address:

Mumbai City, Maharashtra

I had ordered online and made the payment online on 25/02/2015, however i did not receive any order no. and the amount of Rs.519 got deducted from my bank account. When I contacted mcdonalds on 66000666 they said that due to technical reasons the order was not placed and the amount which was deducted would be refunded within 5-7 working days. I tried calling up the office at 49135000 but din't really get a positive reply.The amount is not yet refunded in the bank account.and asking me to share my bank statement so as to get the proof that money debited has still not been received by me. why do i share my personal account details.. why dont they keep on their records?????
