I have some experience, but it is all prior to Covid.
Basically QR (the airline) won't lift a finger to help you with PC (the points people) related problems. I've had multiple issues being caught between QR and PC the last year before Covid hit, and basically QR will only shrug and refer to PC, and PC will only have people available 08-16 local time in Doha, and PC people will just refer you to the rules.
I decided to empty my account, and just did it in time before Covid hit. Haven't flown in 12 months, but given how things are I would not have hopes of them lifting a finger to help you since they all can point to you making a mistake.
