Petrol cap still not delivered!!!!

On 05/01/2018 @ 12h48 I was on my way back from holiday to Jhb. While filling up my tank, the attendand, Sifiso, didn't replace my cap. When I contacted the manager, Dees, on 06/01/2018, he assured me that they found the cap and it would be couriered to us. Today, 11/01/2018, after numerous attemts to phone him and smsed him, still no reply. I still need an answer!! So much petrol has evaporated that it's a joke!!
