He is not a current customer and his updated review is nothing more than a revenge rating.
The only reason he is updating his review is because he wants to see us out of business because his abusive behavior led us to ban him from our service. It is sad that this website lets people like this drag down providers who are in good faith trying to provide good service.
From the responses from your customers, it does not appear that anyone will take him seriously. As one of your satisfied customers for several years, I don't.
