If you own any .com domains – you may be contacted by this company to renew your domain, i suggest that you immediately file any correspondence in the shredder so that it’s totally secure and you don’t unexpectedly pay at least twice as much as you should for your own domain.
Note that if it’s a popular domain – it’s going to be a lot more than twice as much – i know one person who got quoted a couple of thousand pounds to renew through them (for a year)- the latest one i’ve received (shredded) is for twice as much as it actually costs.
