I've been exchanging emails with Tanga for a few days now and today they've sent me basically the same email as they've sent you two, and I further pushed them into telling me WHO received the subscription – their clearing house or the publishers at Backpacker. They claim that Backpacker magazine is "processing my magazines" and I'll get them shortly – that Tanga doesn't know how or where the order got hung up, and that they're surprised that it happened.
I just called Backpacker's subscription department (1-800-666-3434 – I suggest you do as well) and they've not received any subscription information for me.
I'm now calling Tanga, so we'll see what happens.
EDIT: Can't find a phone number for Tanga (surprise). So I emailed them again. I think I spent $5.86 with Tanga and I couldn't care less about the money loss, but I'll not be pushed over or scammed.
