Paying double for Bloods (Cash & Medical aid)

I had continuous blood draws for the last 6 months paying cash on medical aid rates, its small R 230 right, now when my husband and I went in for multiple draws (More than 1 tube) we asked the lady at the reception VERY NICELY can we please pay CASH for the draws cause we saved up for it and I DONT want to use my savings, to my surprise we get a claim from our medical aid that it has been paid out of our savings, I'm fuming cause its May and now our savings are up for the year. They can repay my money yes, but I don't care about that - People need to start listening to the patients, we deal with it financially not you. so please don't do it again Kloof Ampath, please listen when we request differently - we do this for a reason
