I have had two recent problems regarding MileagePlus, and their "help" desk has caused my blood pressure to rise, temper to flare and finally, my hair to catch on fire. On the first problem, I booked a Hilton room on united.com with a special offer of receiving both HHonors Points and MileagePlus Miles. Upon arrival at the hotel, they tell me the room was booked with Expedia and I would be receiving no credit on either account. After a couple of unsuccessful calls to United (nobody there knows how their hotel res system works), and one to Hilton, I wrote to them with the details. Their reply was a canned letter telling me that I need to have a Hilton Hhonors account to use this benefit (I do), and then it gives the basic details of how to use the HHonors web site to choose "points and miles" as my default setting. I already had that, but this was a UA special offer. Last night I bought some RDMs for my daughter, as they were only $0.21/mile and put her over the top to get a free ticket on her next SJO-DFW trip. After waiting for the payment to be processed, I get a page that tells me to try a different card. I checked the card website, and sure enough... The money was charged to my account. It wasn't listed as "pending," but rather as "completed." My email to MileagePlus received a reply this morning with another canned reply telling me how to buy miles on UA's site. Anyone have a hair-fire extinguisher? I'm so tired of having to spend so much time on this stupid stuff. Has anyone else here experienced similar problems with their service (or lack thereof)? I don't even know where to turn for help at this point.
