Doubled billed

My account was debited with meds that we did not get. Apparently it was delivered at the wrong address. What had happened to it, I would like to know.. The replacement was claimed from my medical aid and they refuse to reverse the meds that we did not get.

Now they expect me to pay for meds I did not get.

This not the first time that it happened to me.

Why must we work through a company that can't deliver.
