Well, what do you know. I replied to one the recent newsletter emails from Prodos which had a person as a sender. I explained my situation (my email and address had changed since the AvP pledge manager account was created) and asked about my pledge. I got an answer the next day with a link to give my current details - and today I got a message saying that my pledge was partially sent with a list of the minis. So it looks like it paid to contact them once again. This time maybe the right person read my message?
I had send a couple emails earlier, changed my address details and added a note in my pledge manager with the information about my changed email address. That didnt work at the time.
But I will let you know how it goes.
