Query: Beautiful but mine were defective.

These boots are so beautiful and I thought these were going to be the best boots I ever bought. But sadly the two pair I bought had a defective left heel.They fit well and at first they were so comfortable. But the left one on both pairs felt as if the heel had not been made correctly as after a short time of wearing it my heel started to hurt. I had not realized this until after I had left for the day, so after a few hours it was unbearable to wear the left boot. I was so disappointed.Since I had bought two pairs and both had the same problem I chose to have a refund instead of trying to get an exchange in fear that an exchange would be defective as well.
