I had no issues with him, and I did a 4 figure deal. There was a hitch with one of the names and it took about 2 weeks to get straightened out (registrar at fault), but it was all resolved in the end.
As Mr. Webname stated, eight hours is a pretty unreasonable time in which to expect a resolution. Give it some time. Sometimes these things take a day or two (or heaven forbid) a week to complete due to various complications that may arise.
