They lost my bags

I checked in two bags at Dubai, connected flights in Kenya to South Africa, arrived in SA at 11, my bags were nowhere to be found, the service consultant for Kenya Airways said they will come with the next flight which was at 4:10 pm, waited at the airport for my bags. They told me it takes an hour for the bags to be offloaded and checked. That took two hours. Later they tell me my bag is coming with the modnigjt flight..they found that out at 5 but they told me that at 6. I waited for my bags from 11am, It is 21:00 I still do not know where my bags are. They keep telling me stories that change. Kenya Airways is cheaper but the service is very poor. If you want to lose your luggage fly with Kenya Airways.
