Brian, that bites!
Sorry to hear that you're going through this, but, it will get better..
I've been in the electronic cigarette / e-liquid industry for about 5 years, and as mentioned above, we've dealt with the same thing..
*Big Pharma and Big Tobacco started losing 'customers and money' to our industry, so, they're doing everything they can to shut us down..
The problem really IS with politics. Certain groups that don't like what we're doing have a lot of pull using their lobbyists,
and they'll either strong arm, or, they'll buy out certain things, and then impost their own restrictions, etc..
Paypal has done it for years - Krale in the Netherlands had PP screw them over...
[And Sqaure too]
We've had Paypal screw Us over, we've had countless credit card processing companies drop us OR try to force a high % fee/rate..
On top of that, what they do is deem certain things a certain way so they can also add 'sin tax', etc.. It's unreal..
We've sold CBD for years - Since before people knew what it was and before it became popular..
As soon as everyone started catching onto the benefits, *boom* another credit card processor would drop us..
Same BS, and, the same with website hosting companies..
Guns, Tobacco, pic - They're all being lumped into a category of 'high risk' or 'sin', so, they can continue to do this sort of thing..
High[er] regulated / Higher rates / Higher taxes . . .
Certain sites / processors still run under non-discriminatory trade and business practices, but, they're few and far between..
Square - Ha.. Yup, go figure.. We used to use the little plug in Square scanner for if we went to events, expos, etc..
Not anymore..
Best of luck man, and hopefully everyone gets resolved for you Much Sooner Than Later.
