Unhappy with the service I received.

Yesterday I went for an ultrasound scan, because I wanted to know the gender. The Dr explained how I will see the difference between a girl and a boy. Then he said its a girl. I didn't even see a thing everything was not clear where I felt I should have just taken my R400 somewhere else. The picture he captured only shows the head because that was the only thing that was clear. The scan even gave me a different date from the 2 scans I had already done. The scan I did for R250 when I was just 12 weeks is much clearer than that and now I'm 27 weeks which this one said I'm 24 weeks. I felt ****** and really not satisfied. I think something was wrong with their scan he just did it because he wanted me to pay. It feels like trauma.
