How to contact someone at amazon support?

My account was deactivated last year due to no issues on my end, all deliveries had tracking, all items were fulfilled by myself and delivered within the timeframe provided. Amazon suddenly restricted my account because i maybe sold 500+ items in a matter of days, what can i do if my product had demand?

Anyways, now my £4000 is stuck in the reserve fund and available funds showing as £0.00 since 23rd July 2024, amazon keep giving me the same automated response.

What do i do? Who do i speak to?
