Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Very slow exchange

The sizing charts on amazon are different than on clogs central. Follow the one on clogs central. I wear a 9 and ordered a 39 which was too small. I sent them back the next day and had to pay a lot for shipping, it has been a week since the company received my shoes and no word that they have processed my order yet. If you need to exchange your shoes, beware its going to take weeks.
