Etsy Account Suspended After Listing Renewal

I recently renewed the listings for my products on Etsy, only to receive a notification claiming that my account was suspended. Because the message came from the Etsy app, I didn't suspect foul play. I assumed that such a major firm would not operate in such an unsecure manner. To my dismay, I typed my card information. My card was subsequently charged several times. Despite speaking with customer service, they refuse to admit their error. I'm going to expose Etsy's lack of security on whatever site I can discover. The answer relies on the responsible organization adopting the essential steps. Did you grow by victimizing others?
