Stripe Stripe Scam- accepting bad credit cards then charging small online businesses huge fees! Internet

I opened up a little online shop on Spotify and was happy when I received a couple of large sales in the amount of $1600 each.  In the end, I ended up paying Stripe (the payment processor) over $400 for each payment on top of having the original sale amount pulled out of my account because the payments were apparently from stolen credit cards.  

Thankfully I have a long fabrication time for my custom rings (4-6 weeks) or I would have been out very expensive gold merchandise as well (aside from my labor costs and time, which I'm also out)!  I emailed Stripe (found no phone number for them), and got replies via email but basically no real help or answers, I was pretty much told 'too bad'.  The fees are very high in the first place, then they added on additional fees for the chargeback and pulled it all from my account without warning.

In my opinion, Stripe allowed stolen credit card payments (with different mailing addresses...daaah) to be put through and so THEY should be the ones held accountable.  The rep I emailed with was nice but would not give me any info when I asked about it.  I had no idea I would be charged so much money when I have done nothing wrong and had nothing to do with any stolen credit cards!  I feel I've been taken advantage of- I didn't ask for this!  Stripe allowed bad cards to be processed, and then charged me hundreds and hundreds of dollars when the real cardholders filed chargebacks.  I have a feeling I'm not the only one this has happened to!  Anyone else have this happen?  Please let me know, I want to stop this!!!  As small business owners we don't have much help or backup to fight the big guys (payment processors in this case) from taking advantage of us and taking our money.  Very frustrating.
