Negligence

I was issued a prescription by the doctor. I went to this pharmacy to get medication. A week later I do not get better instead became worse upon my follow up with the doctor. The doctor discovered that the medication issued to me was not what she had prescribed, she then called the pharmacy and informed me whom to go to. I get there nothing was done about that, not even an apology. Instead I had to pay for another consultation with the doctor which was not going to be needed have the right medication been issued to me. And still pay for the medication which was initial prescribed. What if something could have happened to my unborn child?
