Trying to return whoop free trial

I’m trying to return my whoop before the free trial ends but when trying to it’s saying the country I’m trying to ship from ( United Kingdom of Great Britain and Northern Ireland) doesn’t match and says I can only ship from the same country where you have received your whoop and I need to update my address, when trying too the uk don’t even come up as an option to ship from, I’m so stuck on what to do, I try to contact the whoop support but you don’t get any answer from them

Has anyone else had this? And can point me in the right direction of what to do please!
