State Bank Of India [SBI] — OTHPG PAYTM transaction without knowledge

Address:

New Market, Kolkata, West Bengal

Dear Sir,
This is to inform you that Rs. 21000 have been debited from my SBI account, Kolkata, WB in the span of 12 days in the form of 6 transaction (5000, 4000, 4000, 2000, 4000 & 2000) without my knowledge or OTP. It is showing OTHPG PAYTM for all the transaction. I do not have a paytm account nor did i use my debit card for any online transaction in last 1year. I came to know about these transaction when i went to bank to update my passbook. I have blocked my debit card by calling online center. I did not receive any support from the bank. I am helpless and looking forward for your support.
