[Amps] What's with RF Parts?

[Roy]

A month and a half ago I returned tubes under warranty after obtaining an 
R-number over the phone. Now they do not respond to email inquiries nor to 
phone inquiries left on the answering machine after the 'screener lady' 
transfers me to the tube-man's extension. I have been a satisfied customer 
for 20 years and have recommended them on here many times. Has anyone else 
had similiar experience? Is business that good...
