complaint

on the 18th of Feb 2016 I was stabbed and I called an ambulance to take me to the nearest hospital,within a minute the ambulance was there,My problem is when they arrive at my place they use their torch to check how deep was the wound and and they told me that it was not bad there in nothing that the hospital can do to me and I even told them that I'm 23 weeks pregnant and I was worried if something happens into my baby .I asked them if they do have any first kit in their ambulance so that at list they can provide me with any first aid even to check my BP since they were with me and they said NO.I was very shocked and confused of how come they don't have first aid kit in their cars.The only thing they did they asked me to sign to show that their arrived into my place but no service was provided to me as I am the one of their patient,Please advise on what to do because I was not happy about the service that rendered to me on that day.
