Cancelling AP score(deleting it) how long does it take?

I need to cancel some AP scores, I’ve graduated already but I’m applying to school later this year in a different country and I got some very low scores. So I faxed them the cancellation form like a 9 days and it needs to be done pretty soon(like at least in 10 days from now on). I called the AP services but the woman was very rude and so I didn’t want to talk to her. She said that it will take “months”… I asked her if she could check if they received the fax, and she was like “no.”. Anyone done this before and how long did it take you?
