WORST QUALITY EVER! I ordered 3 shoes online, I go...

WORST QUALITY EVER! I ordered 3 shoes online, I got just one with the same details, second one size 12 instead of 14, the second one another model and another size... and the worst thing the right shoe, I tried for once and I cannot even walk after!! And the manager in Carrefour refused to returning or change it!!! That's so ridiculous and not acceptable... it's was my first and last time with this brand.. precious advise: yeah the models are cool but quality and customer service ZERO.. GEOX all the way.
