HDFC Netsafe Card Isuue
Balance reduced automatically

I have an Easyshop International Debit card. I opened my account on Netsafe on 20/2 and registered my card.

I checked the balance and everything was OK.

I used my card for Online shopping on ccavenue.

I last checked my account balance on 21/2 and balance was OK.

Today, on 23/2, when I checked my balance it was less by exactly Rs.100000.

I checked the used cards list and there was only that card that I used for online purchase and no other used card which makes one thing clear that it is not the work of another person.

Also, I keep my Debit card in a safe and I am 100% sure that no one has made the use of card to withdraw this huge amount. Also, you cannot withdraw this much of amount in one day.

Then how is the balance reduced?

Is it due to the fluctuations in the Share Market or else?
