They keep sending wrong medication

I’ve just about had it with trying to communicate anything with pharmacy direct. It’s like talking to a brick wall. They keep sending me the wrong brand of pills. I specifically told them to send me the brand that has been prescribed by my doctor as per doctors orders. The doctor advised that I use Lomanor but they keep sending me Pendine. The keep sending me a different brand. This morning I woke up to an email from my medical aid saying they have submitted a claim. They still claimed for the wrong medication. Please fix this before delivering this medication to me. I don’t get how a pharmacy dealing with MEDICATION can be so nonchalant about people’s needs.
