Dear vardiaenterprises18-5,
Greetings from team eBay!
We are sorry to know that your account has been restricted due the transactions being counted under the Bad Buyer Experience (BBE) evaluation. Unfortunately customs is a government agency responsible for regulating shipments entering a country.
Please note that eBay has no control over customs and generally, buyers pay any additional costs associated with international purchases, such as duties, taxes, and customs clearance fees. Hence in this situation it is best that you please connect with your buyer to resolve this issue and as a best practice choose logistic service providers that can help with custom clearance for the shipments at the buyer's end.
For more support it would be best that you connect with the eBay customer support team at https://www.ebay.com/help/call_us?type=ContactUs&topicId=4000
We do regret the inconvenience faced by you.
Regards,
eBay Team
