WordPress Domain and WordPress Account

Hello,

Long time after created a wordpress site address, today I received an e-mail with the site address and password. I have reached the dashboard, but with that e-mail where I received those info I am not able to enter to the wordpress admin to see the sites/blog created there. I believed this wordpress site wasn’t opened in a wordpress.com. Is it possible to create a wordpress site/blog via www.remarpro.com?! Please, what should I do? to delete this wordpress address site?
