I purchased UDP a while ago. Black Friday sales roll out and its 50% off UDP. I go to cancel last week. Error - unable to cancel. I call them, they and they say they can't cancel either. Not to worry thought system error should be fixed in 24 hours. Of course not fixed. Try 100 times a day online. Call every other day. Same message but told not to worry the sale prices go till 11/25 and it will be fixed by then.
Now the 25th and not fixed. I call back again. They confirm they cant cancel and that their has been a ticket open on the item to IT. They tell me their are a ton of tickets with people having the same problem. I explain to them that once they fix the problem and are able to cancel the sale price will no longer be available and could even be higher than what I paid. I asked if they would honor the Black Friday price at that time. They said no - if that isn't the price at the time they can re-book they can't honor it. I asked if they could just give me some type of credit for the price difference and just leave as is. They said no. I asked if there is any kind of recourse or consideration to fix this. They said there is nothing they can do. They did apologize for the inconvenience though!
I got a screen capture of the sale price, maybe I can escalate it later but I doubt it.
