Name reservation CIPC

I have submitted proposed names to register a company and all the names I prefer have been rejected. What is worse is that everytime you submit you have to pay R50,00 and in total I have paid R150,00 but to date the company I registered does not have a name. I have before submitting checked online if there was any company in South Africa with the same or similar name. I saw 3 that had similar names different industries and I don't know how those were registered but I keep on getting rejections,
