If you have an order cancelled, or make a return, make sure you check that you have received credit, and the correct amount of credit! I purchased a jacket back in February and I kept being told that they would investigate why it hadn't been delivered, and get back to me in 48 hours. I finally asked for them to cancel my order, but my jacket arrived a week later. I had already purchased a replacement, so I mailed the jacket back in May (yes, it took that long to ship!) I was charged $192, and I used $35 in points. My points were removed, putting me into the negative, and my credit card was refunded $162. I called and spent 45 frustrating minutes on the phone to resolve. The agent asked me to hold while he called the merchant, and I was then transferred to someone else. This person told me that he has no idea who I was speaking with, and that I would need to start over. I hung up and filed a dispute, I wasn't going to waste another 45 minutes of my life!
Another issue I just noticed, I cancelled an order that I didn't receive my points on. Glad I checked, because they did not reinstate the $35 in points I used, nor did they refund my $85. I have spent more time on chat lately than I have spent shopping.
