Paytm Mobile Solutions — Money in my wallet is deducted without my knowledge

Last week there happened 2 instances where money from my wallet was deducted for somebody else order to food panda. The transaction happened from some other mobile and that too without my knowledge or any OTP. i just got sms that money is deducted from my account for an order which I don't know.
I send multiple mails to paytm on this and it is such a disgrace that they did not even respond to the complaint I have raised.
Paytm wallet is not at all secure and anyone who has your mobile number can access your money. So please don't use this insecure gateway for your financial transactions.
