Faire: Sell Wholesale

I installed this Shopify application to try to increase my money,
after more than a year after installing it I had an order, a customer wants 80 pairs of sunglasses for a total of €1,500, I shipped the order and FAIRE has never paid me since February 2024 .
At first, they blocked my account on the grounds that I shared sensitive company information with the buyer, which is incomprehensible and impossible.
Subsequently ADYEN their platform asked me for information on my company, identification, IBAN, my identity card, I gave them everything but each time they tell me that something is missing and never validate, never giving me never clear instructions to resolve the problem.
Subsequently, I contacted customer service several times, no one competent to help me resolve the problem, each time the same generic email which does not help and does not advance anything, a certain Roger, stupider than him you die!!
So by harassing them, instead of paying me, they blocked my account, so that I would stop asking them to pay me, FAIRE and ADYEN big ROBBER.
It's clear that it's a small, insignificant company that will soon come to an end.
Shopify doesn't help me, Shopify puts me in contact with this robbers but then takes no responsibility.
It's not €15, €1,500 is not a fortune but I will get everything back, down to the last cent.
From France I am going to file a complaint with the police against the seller, FAIRE and ADYEN.
I don't recommend this platform, there are much better than them, don't waste your time or money,
And thank you again Shopify for doing nothing
