Oh dear, how bothersome.
How many days away is the return flight? Where does your journey originate from? (Not sure if EU261 protections applies)
Don't make any rash decisions, and don't get forced into accepting any change you don't want.
For example you can probably push to be flown to Bangkok, Kuala Lumpur, or Singapore on a regional carrier and connect onto a QR flight from there. But let some advice trickle through here once you confirm some of the details I have suggested the forum needs above.
