They didn't exact call me but the number may be a scam. Got an email from  < http://sicorp.org.ua/ > concerning making arrangements to buy products from me. I read their initial email and click on their site which talks about arranging letters of credit.

According to  "Whois" search the url ext. does no exist.
I dialed USA number and got a fax their website said tel/fax for this number.
They do have other out of country numbers.

don't know if they are scam but at this point i wouldn't do business with them.

Can you find out who is behind this number?
