CVS review: Meds where not mixed right

On Monday March 4th my daughters doctor sent meds over for my girls they where both sick. They where both spose to have enough for 10 days each. The plain amoxicillin was 5 bottles worth and the baby had 1 small bottle. My mom gave her the first dose and I came home after work to give her the next round. I pull out the 3.5ml and the syringe was so far down to get any meds at all. The bottle was barely half full. My grandparents had her the next day and he went to give it to her and said it's SUPPER chalky and she got enough for barely a day.. they brought it back to the cvs and asked the pharmacist manger and he took it, added water and gave them the SAME bottle back and said it should be good now... at this point they didn't think nothing went home called Me. I called her doctor, her doctor told me to call poison control and they told me to bring her to the hospital that the potassium was way to much for a baby... I brought her in they did blood work and her potassium is alil high for a baby. I called the guy later that day and asked him how much she got because he just added more water to it and gave us the bottle back. Never asked if she took any yet. He was rude about it and wasn't paying any attention to me. Seemed like he didn't care if my baby got sick from to much potassium in 1 day because they didn't mix it right. She's going to see her doctor about her high levels because that's not good for her heart. I have all the paperwork from the hospital and her levels on it. I made copies of it even. Please I would like to be called and talk to someone about this because they could have really hurt my baby. Who knows if they messed up somebody's order also.
