Unacceptable service

Ordered my chronic medication which I do monthly from Discovery medexpress. Their delivery service used is Skynet. My account was debited on the 2nd of December got my medication and told it was dispatched from Dischem on Friday the 3rd of December. Reason I use medexpress is for convenience to not have to go to a pharmacy. I then received a message to say my delivery has been completed on Thursday the 9th of December almost a week later although no medication has been received. After contacting discovery I am told they will get medexpress to contact me. They are then in contact with Skynet whom advise they delivered my medication Wed night at 920pm..firstly who on earth delivers medication that time of the night and I have camera footage proving nobody arrived at my gate. I then get told 3:15pm in the afternoon the driver is on his way so I hold off on going to the shops.. Wait till 5:10pm then had to call discovery again as my query was apparently resolved.. Still no delivery. Everyone closed at that time.. Another day no medication!!! I then get a call Friday MORNING after 9am from medexpress do I have my medication.. NO I DON'T! Then another call after 10:30am advising the driver delivered my medication to Bonita yesterday and had to go collect it??????? How can you deliver to an unknown person plus apparently my suburb was unknown yet it's selected on my app, secondly Skynet are based in the exact same suburb and 3rdly they been delivering here almost a year and suddenly don't know my address???? Another excuse they couldn't get hold of me as they have an old number. Discovery and medexpress have my number. All the times they called, why could the driver not confirm my address nor the number. Another lie the driver arrived at my property again last night. We were home and have cameras. Nobody came here. Was given the managers number but he seemed to not be bothered and would just be sure the parcel is delivered, not bothered about lies or any of the above. Will also bring this to Discovery attention and medexpress! Unacceptable when u delivering chronic medication!!
