While i am sorry for your loss, you should've done some research before jumping into such a mistake.
In the heat of the moment when someone offers you $100+ for pixels, it's easy to get greedy.
You also seem to forget that not all employees of gold4rs are actually working for them, they are themselves, and even the employees can get greedy.
Their horrible spelling and punctuations and grammar should be obvious pointers to people that there's no way to do anything even if the sale goes abruptly wrong.
But, only recently on sythe there's been alot of problems with the account sales and what not from these businesses, not only Gold4Rs but also Usfine.
Lesson here is to only trust someone that hardly has a bad reputation if any at all, seeing as back in the day gold4rs used to be HUGE with the scamming.
Finding a business which is trustworthy is hard, because one employee can fuck everything up and set off a chain reaction.
TL;DR
Sucks for your loss.
Next time pay attention to complaints and reviews.
Sell/Buy to someone trusted on sythe.
