@AsmirS if your rating deviation was higher when you lost the points than when you got refunded that may be part of it.
For The Forum:
Also, this whole "2000s" are novices crap is crap. It only goes for some, and mainly the 2000s that strictly play lobby games or tend to play lower rated players. There are plenty of under-rated and over-rated players for all ratings and you just need to accept that.
