I like United redemption customer service line, they are willing to find you a seat for miles, but that`s about it that I like about United Mileage Plus program. This is due to they scamming partner Vesdia, Inc, aka MileagePlus Shopping. They do not transfer my miles to my United account though retailers confirmed the purchases, and Mileageplusshopping post them in pending status which is never changes (they started to have this behaviour in March, and now they not only keep my miles for purchases, they also did not follow with a promotion) I`ll never going to use them again and do not recommend to anyone! They also ignore my emails (sent 13 of them, got responses twice, saying yeah, you should have gotten them, but when I asked why haven`t I, they just stopped to respond at all. Use reliable middle sites (I personally like mrrebates and mypoints) if you don`t want to be scammed and get what`s promised to you.
