Pharmacy gone wrong

This is specifically for the Clicks Brigh****er pharmacy. I am 20 years old and was given a script by my doctor for anxiety medication, and I was dispensed high blood pressure medication. After almost collapsing twice, I did research about the medication I was on and i went to simply ask for the error to be fixed. I was met with a profoundly rude pharmacist, Vernique Dhana, who refused to acknowledge her mistake, and proceeded to try to convince me that we had a conversation about her giving me medication that was different to what my doctor had prescribed, which didnt happen. After having to reitterate multiple times that I simply need the correct medication and would like to leave after that, Vernique repeatedly tried to undermine my knowledge asking the neighbouring pharmacists whether or not the medication I was issued was for high blood pressure. Her mistake could have caused me so many complications that I cant afford to risk, and I worry if she's done this to other patients too. This is not the first time I have encountered such unprofessionalism at this store either.
