Query: BEST CUSTOMER SERVICE YET !

After receiving an item I had a problem so I contacted their customer service. This is usually when a vendor fails, however in this case this vendor shined mainly because of the people who work in the customer service area. They resolved the problem and made sure via several follow ups that the problem was taken care of in a satisfactory manner. In my experience this is what keeps customers more than anything! WAY TO GO GUYS!!!!
