Poor online script process

I sent my script throughto clicks and got a collecting notice. i collected and was never notified that they dont have all the medication i ordered. only to find out when i got home. i went back to the pharmacy they dont have a history of my order and online they already showing the next date my script is due. i call ed the call centre and the lady tells me sorry there is nothing i can do, Honestly there is a lot that she could have done or clicks could do. Notify the customer you dont have the medication so i can go to a pharmacy that has everything i was. Enquire wwith other branches if they have the medication and where i can get it dont tell me you there is nothing you can do that means you dont care. You have the initial script where do i get there medication. Whats the purpose of the onlune ordering if it doesnt make an effort to ensure the medication will be complete might as well go straight to the shop an make my own plan. Im sure Dischem has a better strategy than having rude and not willing to help consultants
