Not good but certainly not the Worlds worse.
My Worse ever experience with Customer support for pure "Twattiness" was with Desert Dollar (I knew not of rogues back then)
Afetr I did not receive a deposit bonus I rang them up and asked very politely
"Why not"
Twatty replied;
"'Cos your in the UK"
Me;
"But it says nothing about the UK in your T&C's"
Twatty;
"Yeah it does, no bonus for you mate", hangs up.
Very professional outfit
Have no idea why they would be rogued
