Unable to make a call to seller central support team of Amazon UK

Dear Amazon,

We tried calling the Amazon UK Seller Central Support Team but couldn't get through, it just showed "Internal Failure" (please see attached screenshot as below). Amazon customer service told us to change browsers, but it doesn't work either. (As you can see in the screenshot we were using the Microsoft Edge)

We would like to know the reason why can't make a call from Taiwan? Does Amazon have restrictions on other international codes?

Hope to get your reply ASAP, thank you.

Thanks and best regards,

Ellie C.
