Mass Character transfers (Customer service deals)

Hello,

I'm returning to the game after not playing since around 2015. I have the problem that half of my toons ended up on different servers (Probably my fault).

I want to consolidate them onto 1 server but not really crazy about the idea of spending 100+ bucks on character transfers. Even if I just transfer the toons I used to raid on I'd be looking at 5 transfers.

So I guess my question is does anyone know or have any experience getting customer service to helpout or workout a deal for migrating a bunch of toons?

Thank you for any help or insight.
