Etsy complaint: Accused me falsely for fraud chargeback

Been with Etsy a year now and out of no where they suspended my account with NO reason. Emailed 3 times to get clarification and was ignored. Tried to appeal even though I didn’t know the reason. They replied saying my account is permanently suspended and yet failed to give a reason. I challenged this. They ignored me. Checked my payment balance to see that I had a fraud chargeback on one of my orders and took my outstanding balance which was £137.80 exactly. Looked into this and seen that this was for an order which the customer said that they have received the shoes and they loved them. Order has valid tracking with Royal Mail yet conveniently they have took the exact amount of money left in my balance. So it is very evident that they received the shoes. Of course, I had no email me informing about this or asking me to send evidence. Unbelievably inconsiderate and unprofessional.
