I can't speak for Facebook, as I'm not on there. But there's a lot of younger and/or newer collectors on Instagram, and some of them fancy themselves as big time dealers. And when you're dealing with other younger or newer collectors who may not know any better, you can get away with a more flippant attitude towards customer service.
This place, on the other hand, is filled with a bunch of cagey ol' cats who are too smart to get over by a kitten. I've never bought from Gem Mint before, but I've seen the guy have a lot of problem-free transactions on IG, and he always carries himself as a solid citizen there. I imagine he'll chalk this up as a learning experience, and become an even better seller because of it.
Thanks Jam
No problem. Now follow me (nosaj80) back, you self-centered .
