thanks for Your reply
YES, sorry, it was 074
i did buy on bookin. com a single itinerary business class
NAP-AMS-MES
first leg operated KLM
second leg operated AM but with AM flight number (no KLM)
so i received miles and mqd for first leg and nothing for the second
submitted mileage credit form, didn't help
contacted delta support, escalated, they contacted skyteam dep which says it doesn't earn miles because it is paid to KLM but on boarding pass there was no codeshare, there was AM0026 flight (in pnr.sh appear as AM/AM)
they wrote
"Okay, I called the skymiles service desk. They are advising that because it was booked directly with KLM and paid to KLM, it would have had to been a KLM flight number/codeshare with Aeromexico. But since it had Aeromexico's flight number, that flight will not apply to your skymiles account."

and
"because it had Aeromexico's flight number on the ticket, that is why it does not qualify for Delta to get credit for the flight. If it had it listed as a KLM codeshare, then it would have qualified for credit."

and
"I have called the skymiles service desk. They are the ones that deal with the mileage credit. They were the ones that advised that it will not qualify for mileage credit. I have shared everything with them. I am truly sorry for that."

and
"Long story short, when you book with one of our partners on their ticket (KLM/074) it has to have all KLM flight numbers on it in order to receive credit. That had a Aeromexico flight number, so therefore it does not qualify for credit."

i gave up
