I have this problem for a couple of years: I usually have a few of request first exchanges in my account with some resorts. But every now and then II will "add" some resort in my request and send me a confirmation. If I did not catch it, I will be stuck in the "not wanted" exchange. No, I am 100% sure I did not make the mistake. I've just been confirmation with a exchange I did not request. And this happened many times before (When I checked my pending request, I was surprised by the resort I did not plug in there). Does this happen to you? How do you avoid this problem?
