So I contacted, again, the retail sales manager. At least he acknowledged me:
"Sorry I didn't respond yesterday, it was my day off. I see the back-order is still open, and it absolutely has been a long time. I will look into it today."What bugs me the most: their payment policy. I had to pre-pay for the "special" order in full. This is not fair now (it might even be illegal). I should have only paid or been charged as I received items. Alas, I won't rock the boat at this stage.
