TRL WON'T GIVE ME MY AMP


Not sure this is right Forum but I'm desperate. I have an  Tube Research Labs amp  that the owner Paul Weitzal made for me 9 or 10 yrs ago.  January 2019 the amp started to cut out,  contacted Paul but learned he had pasted away.  Received email  from TRL  saying  still in business with new Owners.   Gregg from TRL contacted me and told me to shipped it to an  address in Houston which I did, insured for $5,000.  A few weeks later around the end of Feb. Gregg sent me an email telling me the amp was over heating. The 1st of March I email  Gregg with instructions on what I wanted done. That is the last time I had any contact with Gregg!!!!! I sent email after email to TRL pleading for someone to tell me where my Amp is????? The last of week of August,  I sent an  email to TRL saying if I didn't hear from anyone I will go to stereo sites and tell my story!!  Immediately had phone call from  Leon in  NEW YORK asking me "what 's going on?"After explaining the situation to Leon, said "would call me back in a couple days". So needless to say  Leon never called back and when I call,  he is never there and leaving a message does no good.  I'm hoping someone can tell me what to do????IF nothing else, do not do business with "Tube Research Labs"
Thanks Kim

Thanks Guys. The Amp was more sentimental than anything because it  was from Paul. I don't like it when someone takes advantage of a situation. I will make some calls to the  local Authorities.  Maybe I'll take a 3 day trip from Seattle to Houston.  Rent a car and go to address it was shipped and see if Anyone is there? Thanks again Guys

This is the main reason I no longer go to small one or two man operations for my audio.  I owned 3 AI tube preamps but once I heard that the owner of the company was semi retired, I moved on to something else.   All my audio is from big companies like McIntosh, Esoteric, Technics GE, and Sony.  At the very least, if someone dies, the show still goes on.  Hopefully I will never be in the OP shoes.
I will be in Houston on the 31st of October and will gladly go to the shop in person to try and retrieve your amp for you!!!! These people piss me off and would be happy to do that if you do t get some resolve before then!!!!!
What is the mailing  Address ? Let’s do a google street view and see if it looks legit. Maybe Call the surrounding businesses’ ask if they have seen anyone go in or out? Any phone number? They can’t stop us all! 
An attorney's letter is just advisory......just move on.  It will make you nuts to dwell on it. I would guess that the place is now a beauty salon.
