Re: Gmail Problems

There's absolutely ZERO chance that there are duplicate accounts on Gmail, no way no how.
All that's happened is the other guy has mistakenly put your email address into one or more websites including his bank account and so on so those websites are simply sending emails out to your email address.
There is absolutely nothing for you to change here, your account is your account.
You do however need to contact either him or his bank asap and inform them of the mistake.
The more this guy inadvertently uses the wrong email address (i.e. yours) the greater the risk that you will get tied up in all manner of things. He might join gambling sites, porn sites, all sorts of stuff. He might engage in illegal activities.
The issue is simply that someone is registering YOUR email address with lots of different websites instead of registering their own. That needs nipping in the bud.
Hope you manage to reach him.
