Query: Performance let down

Bought this machine from Amazon and it worked 3 times and then died. Used a powerful blender, Vita Mix, and was excited that it made perfect smoothies, however; very short lived! After making 3 smoothies in 3 days, the machine just died on me. Checked the fuse and it's alright but changed it anyway just to make sure. Still not working! Very frustrated. Tried a 200w transformer and thank God, the Vita Mix is sluggishly whirring but this tells me that my blender works and not the 3000w transformer. Googled PowerBright and their website is down. Where do you contact the manufacturer for a replacement. It's driving me bananas! Problem is it was bought 3 months from US and we are now in the Middle East.... and this thing is very heavy for shipping. Is it worth is to spend more to ship it that what the product is worth.
