Yeah these guys are sketchy as hell. I dealt with them first hand. They hold shipments hostage, use other carriers and then there is the double pay mentioned by Jim L. I also do not believe they are insured properly for your cargo. The guy who owns the place (and his driver) own a few other businesses to hide what they are doing and they use fake locations so you can never even reach anyone in person. When their website was active their "head office" had another business there who never heard of them.
Im guessing at this point they closed up shop and started again under another name
