Worst service

I went to Tshepo Themba 2 weeks ago, i told the doctor that he did not assess me properly but he was adamant that i have acute gastritis, he gave me medication which made me worse, I think the standard there has dropped badly, i still have the same problem coz i told him that he must make sure about what he's talking about coz he didn't seem to know what he was doing, the waiting time also to be attended is very long and bad
