Google AdSense rejection

Hi,

I have tried 16 times in the past few months to set up a Google AdSense account for my website but it always gets rejected with the message "You already have an AdSense account", which I do not have.

Each time, they mention that it is associated with a random email address (that does not belong to me).

And unfortunately, they do not provide any contact options.

Does anyone have any idea how to resolve this?

Thanks.
