I could not find this via search so I am hoping someone can help.

Short story is I applied/approved on April 16 for BA Chase card with what I thought was 100k Avios bonus.
75k - spend $5k in 3 months
additional 25k - spend $20k in 12 months
Companion ticket - spend $30k in 12 months.

However, I have passed the $20k and have not received the additional 25k Avios. I called and they say I was only offered the 75k bonus and companion.
I swear I applied knowing it was 100k, but the approval emails, etc don't reference any bonuses.

Is there a way to know to determine the date range the 100k offer was available?

I'm pending "escalation to marketing" response.
