I think people who purchase counterfeit goods under the very false assumption that replica dealers operate under the same conditions, warranties and equal level of after sales services as Amazon or other legal retailers will sooner or later encounter problems and experience disappointments. It's practically inevitable....
I recently ran into a more serious problem than just getting a refund late, but did I open a Karen-thread throwing a toddler tantrum?
Well, if you go through my posting history, you will quickly discover: No, I didn't.
Why is that?
Let me explain: I simply concluded that a minor (while still larger than your) problem didn't warrant risking my relationship with the TD in question (and possibly other TDs on RWI, they read here too, after all!) if I was otherwise happy with the transaction and satisfied with the received goods. Would I have done the same with Amazon in a similar situation? Maybe or maybe not. You can be blacklisted with Amazon too if you abuse your return privileges for example.
Bottom line is, I took the whole situation into account, not just the fact that I was unhappy with a little after sales detail and I concluded it was simply not worth being a drama queen for merely a little hic-up in an otherwise ok deal.
You got your money refunded (as you normally would with a TD), but you waited longer than you would have with Amazon (as you normally would with a TD). There's not even an actual problem! LOL
And the way you are reacting to (rather deserved) criticism for opening a tantrum-thread (even apparently with the intent to coerce the TD, plus you also didn't tell the whole truth!!) for a complete and total Nothingburger just leads to this conclusion: You don't have enough patience for this hobby, you're not cut out for it. You should try to find a new hobby that requires less patience and is less stressful.
Good luck!
