Secondly, my husband has registered with the Dept Health as he is over 60 for the vaccine, nothong from Discovery, nor can you find where to register, say they will contact you................right? Thirdly, Submitted a claim 17/4 for a Dr who made me pay up front, subsequently, they have already paid him twice, on query, they say they cant read the invoice, nobody contacted me
