My husband has to have chronic medication for his cholesterol. We were told by one doctor, Dr De Wit, that we have to send her the medical aid form for chronic medication so she can complete it. We still did this the same day. Having heard nothing back from her after three days, my husband called Intercare. He was told that Dr de Wit is on holiday, but they will pass the form on to my husband's actual doctor, Dr Smit. Again, we heard nothing back for a week. My husband called again, where they searched everywhere for the forms, eventually finding it, only to inform my husband he must come into the practice so they can take his height, measurements etc. My husband went in a few days after that and the nurse took all the necessary measurements etc. We heard nothing back for another week. My husband phoned again yesterday, and they eventually sent him the form. The form was not completed, no measurements etc was filled in, and the doctor did not sign. And surprise surprise, Dr Smit is on holiday. We do not know what more we can do. We just want the form completed to get my husband his necessary medication! Absolutely horrible service!
