I had a great experience with Arnya/Anya just yesterday following a disaster of a call with another agent prior.
Also throwing Jarrod's name into the ring for outstanding service and willingness to log a technical fault with the internal QF helpdesk about an error he was getting when trying to book a partner classic award for me recently. It took a bit of persistence on my part with regular call backs, but the fault being logged did result in the root issue being fixed.
I'm sure the vast majority of agents would have just given the usual "phantom availability" or "it's a problem on the partner's end" instead of taking the more difficult route to get the issue fixed.
