Well glad you got 5 star service because last attempt I tried at buying a Taxi pinball ramp I got no response after 10 phone calls leaving messages and going onsite sending emails etc over 4 weeks? Obviously I wasn't a valued enough customer and ignorantly ignored ????
Don't know why as Im a repeat customer , But you know what I just buy my parts from overseas now where I'm valued and don't get jerked around. Funny thing is the guy is supposed to be a mate who ive had over to my place and organized a machine for etc etc?? Political hobby at times, Those that know me know I'm open/honest and genuine but can't stand pretenders that are out there simple as that ........ Enough said 
Interesting.
Taxi ramps are not a product listed on the RTBB website. A quick check of the producer of the ramp (PinballInc) in the USA and the ramp is listed as "out of stock". So I assume you successfully purchase the ramp "overseas" ?
"Supposed to be a mate" - Sounds like something a little deeper than a ramp. Poor form bringing it up on a forum where Greg is one of the most respected members and his track record is incomparable.
RTBB is the ONLY Australian parts supplier I will deal with. Never EVER had a problem.
