Deteriorating Service

I have been with pharmacy direct for the better part of 3 years and I have slowly seen a decline in their service. The couriers deliver the medication when they feel like doing so and some of the customer service agents don't seem to be helpful with the simplest of queries. I am a diabetic and am waiting for my medication 2 weeks after it suppose to have been delivered. They need to realize that this is people's lives at stake here and the fact that medical aids recommend that we use pharmacy direct should mean that they hold themselves at a better standard that this.
