Calumet.co.uk worst store ever?

Bought a Sigma 10-20 Lens For Canon mount from them, they filled my address wrong, and sent the lens trough 3 different companies to deliver...which was hell to track.

Sent an email requesting a tracking number, but never received a answer..Phoned to calumet...the operator refused to give me..stating that she had to make a lot of phone calls to discover it. I phoned to the delivery company and trough my name they discovered the tacking number. I have sent 5 emails to calumet...not one single response to this day.

I highly do NOT recommend this company to any one, their customer service simply does not exist, and they don't respect their customers.

Besides this, the lens seems to have an AF issue at the wide end.

This seems unreal, but it happened, and I'm not the unluckiest guy in earth.

I plan to call their Manager soon, to complaint!
