18,000 points missing in action en route from Accor to Iberia

I have a similar problem (smaller amounts). I received auto direct debit Accor to Iberia emails in June, following Accor stays, but nothing has credited to Iberia. Iberia said contact Accor, Accor said contact Iberia. Catch 22. It used to work fine pre Covid. Generally ~6 weeks, the avios would appear.

My most recent Sofitel stay from mid September, credited to Iberia following the auto Accor direct debit, in 2 weeks. It would seem the time taken is rather variable.
