I'm sorry if this is not the correct place for this post. I searched every way possible without finding an answer for my question.

Exactly 2 months ago today, I completed the last of 6 flights within 3 weeks with LOT. I asked for the miles to be credited to my United MileagePlus account, which was printed in each of the 6 segments listed in my Electronic Ticket. Well, until today, 60 days later, my miles haven't been credited to my MileagePlus. Considering everything that has been happening with this airline, I will be waiting forever. What is the correct procedure to ask for my miles? Through LOT of through United?

Thank you for any help
