well known scam. Just delete it. There is no such thing as a spam removal list, but people like this try to persuade gullible people that by paying $20 or summat like that, that they will be taken off spam lists. The fact is that spam lists aren't one single resource.
You probably already know this, but apparently you should take care using the "unsubscribe now" facility on the bottom of the spam emails themselves. Doing so simply confirms your email address as a valid one, and ensures the spammer will charge his customer for sending you even more unwanted and unsolicited rubbish.
I know very little about computing, but I have recently had two e-mails, from different people (one my daughter), marked as SPAM, when they were not, so even if you can get a "spam delete service", it could be counter productive
