Shocking service from a discovery medical aid 3 party

We were told that discovery medical aid was sending us an oxygen meter. The driver contact us to say he was in brakpan we then told him we live in eastvale. He tells my husband he doesn't deliver in that area. My husband went on the link and tracked him he was literally 200m up the road we phoned him to tell him and guess what he doesn't answer. Dischem your lack of service is atrocious and non existant
