My phone no. [protected]
I am not having any lpg connection in my name or number.
A message was received on my account stating that
"dear mr parkash chander, a payment of rs 709.5 has been initiated against your order[protected]."
Then after, again a message popped stating that
"dear, payment of rs.709.50 has been successfully received against your order[protected]. Ref num #[protected]"
A transaction has been done from my account for which i haven't requested any service.
Please provide assistance in this regard.
