Golem Banker access
Problem Solved.
Just went to the Banker located in Divinity’s Reach on Dwayna High Road near the Ministers Waypoint.
I was then able to retrieve my little Golem Banker buddy and put him in my bag 
Just gotta remember not to click Deposit All Collectables whilst I have the Golem Banker in my bag as it would mean a trip back to the bank… or leave him at the bank 
Just an FYI — what you pulled from your collectibles tab in your bank is not the Golem Banker, that would be the golem mini-pet. The mini-pet just follows you around. The golem banker provides access to your bank from anywhere in the world. The banker is only available for 5 days, but you’ll always have the mini-pet. Also, the banker was only available to those who purchased the deluxe edition. The golem mini-pet is one of the rewards from the Guild Wars 1 Hall of Monuments achievements.
Just wanted to make sure you really have what you think you’re supposed to have.
It sounds like you just stuck the golem banker into the bank manually. The banker golem is not affected by the “Deposit All Collectibles” option.
The minipet golem is deposited by this option, but you can also get an “invisible” bag and put the minipet golem there. Invisible bags are made by crafting, and the contents of the bag will not show up in vendor sell lists and will not be sent to the bank when all collectibles are deposited.
When you use the golem banker, the golem that you interact with in the world to access your bank will only stick around for a few minutes, though I’m not sure of the exact time. But you can re-summon the golem by using the item in your inventory (assuming its time has not expired).
Just an FYI — what you pulled from your collectibles tab in your bank is not the Golem Banker, that would be the golem mini-pet.
Thx for that Maximus and Nkuvu, greatly appreciated.
I had retrieved the Golem Banker from the bank, which means the little banker must not have been put in there as a collectible, but manually put into himself whilst out and about… oops, my mistake!
Any how, you had me thinking what came of my little mini-pet which I thought I had lost on day one of my journey…. hmm… which in turn had me check the bank again and sure enough, there he is, safely locked away as a collectible 
Thx
