Magicpin — money deduction from my bank account

I had purchased a bookmyshow voucher of 350 for rs262.50 using my card. But the transaction failed and amount was deducted from my account. I did this twice hoping there would be some problem. A sum of total rs 525 has been deducted from my account. I wrote an email to them and waited for more than 1 week nearly. But my money is not yet credited. There is no action taken.
