eBay does not respond to emails regarding my restricted store

[1453customparts]

I have made considerable sales with eBay for 3 years, but my account was restricted 1 month ago. eBay does not even respond to my emails. When will you take care of it?

What did the message say, that eBay sent to tell you that you your store was being restricted?

Did it say something about BBE (Bad Buyer Experience)?
