EXPIRED COLIX DROPS

Bought Colix drops at dischem with an expiry date of March 2020 imagine if the baby had used that, then the manager has a nerve of calling me to ask me to bring t=for an exchange, are they considering the petrol i used to and time conusmer whose going to compensiate that? Not to mention the reputational risk ruined with the mother of the infant i bought these for, and then head office does not reply to my email , i will kindly await a written apology as i have sent the pics with the expired meds and slip.
