Incorrect data after transferring account from fotolia.com

Some time ago I purchased licenses on Fotolia. Now a law firm has contacted me for compensation for unauthorized use of photos.

So I transferred my account from Fotolia to Adobe Stock to show as proof in the case that I legally purchased licenses for these photos. The problem is that after the transfer, in the historical licenses I have the transfer date, not the date of purchase of this license.

For this reason, they reject it as proof and claim that I purchased these photos after their report.

So please help me change the dates on my account or send any other confirmation showing the date of purchase of the photos on fotolia (and not the date of transfer to Adobe Stock).

I tried via chat but after 4 redirects the chat simply ended by itself and I was left without help...
