Address:

My name is Bhavan Kamble. I went to pizza hut to pick my orders at Kandivali Mumbai on 20 January 2017, orders were 5926 and 5926 which amounts Rs.1147 and 1787. a total of Rs.2934. But they deducted a amount of Rs.3669 which they later void (Void sale) and gave me the void sale bill. and I again paid the amount of Rs.2934 from my debit card.
The manager told me that the amount of Rs.3669 will credited to your account in 2-3 hours.Now its 12 days past but still i haven't received any amount.I contacted my Bank (Bank of Baroda).they told me that the amount is credited to the merchants account, so you should contact Pizza Hut.

So, Please Refund my amount of rupees 3669 as soon as possible.or the time it will take to refund my amount.
