When I look at images for my name in Google, at the bottom of one photo are the words "amazon.co.uk". I contacted amazon uk and asked that it be removed, and they said it would take up to 2 days. That was a week ago, and it's still there.
With respect, it sounds as if you have already correctly contacted the right people who acknowledge that they have the right, ability and duty to do what you request. Would it not be best to contact them again, refer to your previous contact and chivy them along?
