Delivery services offered but customers aren't able to receive it via delivery

I'm very disappointed in the service I've received from Clicks. I am trying to move my script from Dischem to Clicks and I loaded my script online specifically asked for delivery. I get a sms back saying it's ready for collection. The sms also has an option for delivery. I click it and complete it. My medication was still not delivered. My medication is R1000 a month, if you don't want me as a customer that's fine, I'll go back to Dischem but reverse the medication charged or deliver my medication as I have requested. I've never had this problem with Dischem and why offer delivery and I am not able to use this service.
