Lost my 4.0 but it won't let me order a replacement? Help please

How do I order a replacement 4.0. Can get to order page but won’t add to basket. Very frustrating

same - i’m absolutley LIVID - I JUST got a whoop, 4.0, lost my battery and now they have only 5.0 - so i have to buy a whole new whoop? WHAT A SCAM!!! and there is no one to talk to. this company is disgusting

Whoop sells the 4.0 battery pack on their website. https://shop.whoop.com/en-us/collections/batteries?order_by=featured

Instead of yelling arroud, maybe a quick internet search would help? There seems to be no problem ordering one from whoop. Here in my country you could also buy them from Amazon.
