Parcel delivered at the wrong address

I sent a parcel on the 18/12/2015 to a customer Adriana Botha, on the 21st, I saw it was delivered and Sharon signed for it. Since the 22nd I phoned every day, until Lindelwa told me that it was delivered to the wrong address, but everything will be sorted out within 24 hours. That was 23rd she promised me that. This afternoon 28/12, I checked my e mail, there was nothing. I phoned again, while holding on for her the call dropped. I phoned again and a Peter answered. He told me that Lindelwa send ma an e mail, which came through while I was talking to him. In the e mail she said that the COMPANY where I sent the parcel too was closed and there was a note on the door saying all parcel should be delivered to a Chatz Connect. My customer doesn't know this shop, neither the Sharon who signed for it. But Lindelwa decided that the case can now be closed, since all my customer have to do is to go to this shop an get her parcel from Sharon! I have all the e mails, plus a copy of the waybill with the address written by myself on it.
