Inexplicable market behaviour

I’ve tried reporting this to support in-game today. My feedback was closed almost instantly with the feedback that I should be patient when selling a player and that I should consider offering the player at a lower price. 

So, like here, also when using support I am completely ignored. My input is not actually read (sorry to say, but that’s an absolute habit of the EA helpdesk; just reply the most generic bits of text, without understanding or even reading the user’s input), and nobody bothers to try to explain why the market behaves oddly and inconsistently for this particular player. 

Remind me: why does EA offer a forum and in-game support? As clearly I’m just ignored consistently.
