I am very disappointed with Pick and Pay Bhophelong Swazz inn

I am very angry with Pick n Pay Bhophelong Swazz inn.I went to buy stuff on Friday last week at around 5pm so I left my bag at the parcel counter.And I was given tag number 79.So when I was done with shopping I went back to take my school bag that I left at the counter and my bag was gone.The lady by the name of Gaisha or Geisha she is the 1whom I left my bag with.Inside my school bag they was my work suits,Packet of Omo washing powder and my documents.Which is passport.I waited from 6 o'clock when I was done shopping up until they where about to close.I asked to talk to the supervisor to report.She told me I must wait maybe tomorrow refering to Saturday someone will bring back .So I went on Saturday I was told by another Supervisor to come on Sunday.I went again on Sunday I was introduced to another guy they said he is the 1 who review camera's.So he said I must come Monday so today I went there I was told the guy who said will review cameras is not there.So they started to change posts.I told them I need my missing back that had my documents inside.And Friday it was raining cats and dogs.So it seems they don't want to be accountable for negligence since my bag disappear inside the parcel counter.It had a Zimbabwean passport.By the way I went to police station on Saturday morning trying to report my case I was told I must see the Store Manager and come into agreement.So now they don't want to be accountable of negligence.All I want is my Bag that went missing inside their parcel counter.
