Rude Unhelpful Staff and Parcel Missing

I phoned this morning in connection with my parcel and gave my waybill. I asked if they could delay parcel delivery as I was out of town. When I called to let them know I'm back in town and if they knew where my parcel was, they asked for my waybill number which I gave. They then proceeded to tell me they don't have my parcel it's at their Carletonville branch. I asked so where must I go pick up my parcel. the call was rudely dropped, not I will transfer you to someone that can help. and from there no one spoke to me again. I tried calling back 3 times and they either drop the call or don't answer. The person I spoke to his name is Dean. A very arrogant, condescending attitude that he has. The courier guys should remove him from working with the public. If his is the owner or manager I pity the people who have to use this company.
