We've had the same name problem and none of the above options have worked for us. I had ticket numbers, boarding passes, etc. After website fails, phone calls, feedback messages, and emails, I was finally able to add my own miles for a recent family trip via the feedback route. We tried the same with my son but they won't add his miles without a copy of his passport (which I didn't have to provide to get my miles). There is no way I'm sending a copy of his passport to this company. Not even going to bother to open M&S accounts for the rest of the family as this doesn't exactly instill confidence in this program. After spending hours of my time trying to get my own miles added and our unsuccessful attempts to get my son's added, we decided to close his zero miles account (after the phone agent suggested it). Nope. They won't close it without a copy of his passport. Since I don't want to go through this every time I fly Turkish Airlines, I'll likely just fly another airline if I have a choice.
