Terrible service

Me and my husband went for a covid test on the 3rd of June 2021 a week after that I phoned Lancet accounts department to get a statement to claim back by my medical aid. They made both payments on my husband's account I ask them that mine and my husband was paid up they told me it will be fix every week we have been following up with them and nothing has been done. I think this is unacceptable as I need to claim back and Lancet is not doing what they told me more then once they will do
