I tried to login into my account to see if there was any response to my support ticket and found that my account has been "Banned":
https://i.imgur.com/ZCKihit.jpgExtremely convenient I be banned shortly after creating this topic. There are only two possibilities:
1. They created a google alert to be notified when someone creates a topic or a post denouncing the dirty work they are doing and identified my account through the support ticket that appears in one of the screenshots.
2. After receiving my message by contact form they decided to banish my account to try to hinder the disclosure the case.
So far, I have not received any email answering my previous contact.
The person or persons responsible for CoinURL are definitely scammers. The biggest problem is the fact that there are thousands of websites, blogs etc with positive reviews about CoinURL, so even though I ended up wanting to test the service.
I would ask that anyone who has gone through similar situation to publish here some information (how much was stolen, when etc.) to get a sense of how much they've stolen and to warn others.
