I had the immense pleasure of pre-paying $52k for a 4 year lease on 3 /20's from a "Kelvin Williams" at ALTUSCGI. After about 3 months of no problems, he decides to revoke the LOA and provide a tunnel for the IPs.. Claiming he needed to undergo an "ARIN Audit" while he applied for more space.. After two weeks of using the tunnel, he decides he no longer needs to honor our agreement and leases the IPs to another person. I was able to announce the space from my colo and make use of the space for another week before his crying and malicious claims were heard by my upstream providers whom filtered the announcements.. Now I've heard from a trusted third party that he's shopping my space around in attempt to sell it.. Because of our contract I had to file a complaint with some Arbitration group in Texas and wait for them to review whatever. tldr; Kelvin Williams from AltusCGI is an unstable , pill abusing, pathological liar. I would avoid him at all costs and under no circumstances send him any money.
