Missing package and very bad service

I am very disappointed with courier guy and pudo lockers, I been using them for years and yaga, on Tues I posted a xl locker and it went the next day, on Thursday my buyer got code and went and picked it up, it was small locker and nothing in locker, she contact me asking what's happening? So I contact courier guy, they can't tell me what has happened but they will get driver go back tomorrow morning and see. Ok. Friday about 12 I saw my parcel is still at hub now from morning so called again, spoke to lady and she said can she check and please hold, no worries, then other person come on phone apologize there was no xl locker so it went back to Hun, I had no problem with when are going deliver? He said Monday, ok. So i said him I just do want my buyer think it's ****. He said no don't worry I am going call her now and explain everything ok great I really appreciate it. This now 19:49 and no has called my buyer. Very bad service. I do not know if my package is at hub or not.
