Diary not received

I have purchased a Diary at the Afrikaans is Groot concert, the cashier forgot to put it into the bag, I have reported it immediately after I realised it was not there, the manager phoned me and said they will send it to the closest branch to me that will be clear water mall. They will let me know when they will do that as they where busy at the concert, I received a call from one of the workers to confirm where it should be delivered when I asked when he said he does not know, I want to know how long does it really take just to send a book to a store
