Pathetic delivering services

I had a terrible experience with Dischem head office and the Nicolway branch. I opted for the delivery service that Dischem provides for prescription medicine. What a total disaster, waste of time and money. They never delivered on the day they said they would deliver, and no communication or apology for being late. Two days after they promised to deliver i had to phone after them. The first time i phoned Nicolway because its the delivering branch, they promised to phone back but never did. They have recordings of this. The next morning I had to phone them again because I only had one tablet left. No apology for being late or for the lack of service, and no communication from their customer care line that I emailed with the concern.
