The phone doesn't bent, perhaps you sat on it, but that's not the point right now, the point is that you MUST contact your local Xperia Care and request a vacuum test ASAP
I have experienced the same fault in my xperia z3+. It was very hot when I made a call with it and when I put it down after the call I noticed it was bent. The engineers took 8 days to come back with a very dissapointing "customer damage" decision, even though i was assured by the manager of the store that it was obviously not customer damage. Ive had all the Sony models and have had no issues until this. Have you managed to resolve your own issue with the bent frame?
do not buy this phone the heat problem makes the metal soft so it bends real easy then sony will charge you over £100 to fix it
