Konran 混乱 – mix-up

I have never seen the same delivery guy twice in the 3 years I have been here, however by some bizarre co-incidence the same delivery guy came back again last night so I got to explain to him that the wrong address was my mums fault.

混乱｛こんらん｝に対して謝罪しゃざい｝ました – I apologised for the mix-up.
