Freecharge Payment Technologies / Freecharge.in — Someone used my email address to create an account

Someone named Sahil used my email address - which is not the kind of email address someone could simply guess - to create a Freecharge account. I just received an email with the subject line "Welcome to Freecharge." The mobile phone number associated with the account is not mine.

I would like to know why someone would use my email address for this reason. Are they able to scam me by doing this? How can I protect myself? Please resolve this as soon as possible.

Also, I saw a message here with the exact same issue from January. To Freecharge: PLEASE do not allow people to use someone else's email address without confirming that the email address belongs to them.

Thank you.

Janet
