I hear you mate, I think they employed the work experience kid to create the code for their financial system.

My account is suspended becuase there is no way for me to pay the invoice, my automatic payment method stopped working and one time payment gives error everytime. 

Also, after I sold a $650 item to have $90 in fees for it is getting a bit out of hand.

I loved ebay back in the day (20 years I've been with them now) but there are plenty other sites that allow you to sell with 0 fees and actually give better results now day (a particular social media platforms marketplace comes to mind) 

They are facing a mass exodus of sellers because they are greedy and frankly useless at customer service.
