Expired product that damaged my skin so bad.

After purchasing my items, I was given an expired product which I was told it was new & exciting & on promotion,I didn’t notice it was expired al along. I used it then soon after I started having terrible skin reaction which left my clear even toned skin damaged, scarred, patches all over, breakouts & sensitive, I notified the store & Meagan , Jodie & Evan their managers, all they did was say I must come & get samples to try see if they can heal my skin. Then I must buy their expensive brand to solve my own problem. My skin still looks terrible & now they seem to have blocked my number, they do not even respond to my emails anymore.
