Time to buy a Honda?
Seriously, the only reason I've held onto my Triumphs is because I have a shop within an hours drive that hasn't let me down yet. They aren't a Triumph shop, but an independent, but they do have a Triumph trained tech. If they weren't around, I'd be on some other brand....like Ducati,

which is about an hour the other direction from me. At some point you're going to get tired of dealing with the lameness and either look for an independent shop that can do the work, or trade the Triumph for a brand that has a local shop who knows *** they're doing.
