It took Postbank 10 years to tell us that the full authority my father gave me over his Postbank account in front of a German Consul in Australia, with both of ours full identifications and signatures witnessed too, is not valid because my father's signature didn't match their decades-old sample.

My father is 92 and now has advanced dementia, with his symptoms already starting all these years ago affecting his signature. But the signature was witnessed by a German government official!

So that 'information' was provided to me in a letter as a reply to my postal correspondence from 2 years ago, to essentially tell me that the authority is not valid. In the meantime, I have unsuccessfully tried to get any sense out of them via emails.

As nothing was progressing and I had no trust whatsoever in sending again documents to the ever-changing addresses they gave me, 1 year ago I sent all the documents they requested to my cousin in Germany. He went to a branch and asked them to forward it to the appropriate persons. This has obviously not happened as I am not getting anywhere.

I sent the evidence of my father's changed address where he has been residing for years (e.g. official Australian correspondence, his bank statements from Australia etc) but they keep banging on that only he can change his address by presenting to a branch in Germany!!! Then if not, he should get this verified by some bank clerk or accountant in Australia. So confirmation by these people carries a greater weight than a representative of the German Government in Australia!!!! Although I also sent a document witnessed by an accountant...

But they continue to send statements AND a new credit card to that old address because of the "privacy and security". So we keep paying for postal forward service so that we can at least receive statements even if not being able to access the account.

I am beyond frustrated and angry. I am travelling to Germany soon, but just don't know where to turn and what to do.
