... opened my account spent rest of the night unsubscribing to mail i never asked for so all is ok ...
No, it is not all OK.
NEVER reply to, respond to, click links in spam.
NEVER give any information to spammers in any way.
The spammers probably bought your email address from some other scrote, along with millions of other addresses. The scrote who sold it probably made most of them up, so the scrotes who bought them had no way of knowing which were genuine and which were not.
By unsubscribing to mail you didn't subscribe to in the first place, you have confirmed to the scrotes that your address is genuine. They will now sell it.
The correct way to deal with spam is
1. Filter as much as possible using junk mail filters, so that you never even see it.
2. Report any that gets through the filters to the responsible ISP. It is not always easy to know where to report it, see link below.
3. Bin it.
Here is an outfit which you can send all your spam to. It's where I send mine. They will report it to the right place for you.

Just to repeat the warning:
NEVER RESPOND TO SPAMMERS. DO NOT CLICK ON "UNSUBSCRIBE" LINKS IN MAIL TO WHICH YOU DID NOT SUBSCRIBE, THIS JUST CONFIRMS TO THE SPAMMERS THAT SOMEBODY WILL READ SPAM THAT THEY SEND TO THAT ADDRESS, SO IF YOU RESPOND YOU WILL JUST GET MORE OF THE CR@P.
