Cannot get hold of the branch after receiving someone else's medication

I was at Dischem Clearwater Mall on Sunday 7'th June 2020 to collect my fiance's cholesterol medication at the collections counter, the name on the packet was correct, but when we got home we saw that we had received someone else's medicine. By the time we got home the store was closed so we could not go back and query it. I have never been asked to open the packet and check before accepting the medication before, I normally check the name on the packet and trust that being a pharmcy and the nature of what is being dispensed, extreme caution is exersise before medication is dispensed and you are called to collect. That being said, mistakes do happen. My frustration is not so much because a mistake was made, it's more due to the fact that I have tried to contact the store 5 times today and on every occasion I have been cut off. I cannot go in physically as I am at work, and I cannot make it there by the time the store closes. I have even left a message online for someone to contact me, just so I can explain what has happened. Please can someone give me a call so that we can possibly rectify this, I dont want to leave it too long without letting the branch know what has happened, so that at least when I get a chance to go into the store, the Dispensary is aware of what had happened. In future I will open the packet whilst I am in the store before accepting it. Also please can you ask the staff to inform customers that they need to open the packet and check it before leaving. I would really appreciate a response, as I cannot get through to the branch at all and I would like to rectify it so that we can get the correct medication.
