Extremely poor service and lack of responsibility

Dischem advertises free delivery of one's chronic medications, but they don't grasp the necessity of such a service. I sent them an email to remind them of my order, and it was completely ignored. This is extremely terrible service and a lack of accountability. I followed up and said I would pick up my delivery and move to Click; I was just given the script to shift to their opposition; I did not receive an apology. I now intend to escalate all problems I've had with them to a far higher level of authority, such as sending out expired prescription, refusing to exchange a damaged item I bought, and the abjectly bad service. No less treatment should be shown to paying customers.
