Update: This morning I woke up and saw 72 airmiles x 3 from the 25x event and 3 base airmiles x 3. Why 72 and not 75? So I wrote to them and asked and they replied that they added 18 airmiles to my account this morning as well as the 100 bonus miles. So at least that's over and done with.
BTW the Best Western travel card is available right now. I just cashed in for one.
