Have submitted multiple complaints to them about one of their customers who hosts a scam review site www.webhostingstuff.com who is posting defamitory (untrue) information about our company cfmxhosting.co.uk.
If you contact webhostingstuff they simply block your IP address from viewing their website and block your emails from reaching them, which they have done to us, so rtried contacting softlayer.com who the host for webhostingstuff, but they also ignored us.
