I store lost my Iphone

On 26.02.2015 I brought my IPhone 5 in for repairs at the Apple Shop in Namibia. I was told that they were able to fix it and that it will be done and ready for collection by Wednesday. On Wednesday I returned to the store but they were very busy and were unable to assist me and I left without a phone. I returned to the Apple store on Thursday 05.03.2015 to finally pick up my phone
