Customer service sucks!
Ordered a mask through Amazon, it was defective. Contacted Amazon and Castlegrade, received an email from Dan@castlegrade, told me to order another mask and will be refunded. I did so, after several emails have not received my refund nor have I received any responses from my numerous emails. I finally contacted Amazon they allowed to return the original mask for a refund. Love the mask but their customer service sucks!
