Permanent stunlock

started getting stunlocked permanently on high tier maps; a normal pack rolls onto me, and stunlocks me for the duration of 8k energy shield. I can't move, I cant dodge, no diminishing returns/safeguard on the stuns, just a non-stop barrage of small stuns that won't end or give any chance to counterplay, not even for the smallest window.

Same happened with:
-Ritual Tornado effect
-Doriyani lightning spray
-King of the mists Tornado effect.

I've been stunned and heavy stunned multiple times before and know what it looks like and how stun thresh works; however, these instances are actually bugged. I already deleted my character and I'm done for the league, but I'm 100% positive this will come up again from different users. Completely unplayable
