Affinity Health Issue Approvals/Authorisations and Negate on them

I have successfully subscribed to Affinity Health as a Member in good standing, for the past 3-4 years and have paid all my monthly dues timeously, without fail, via bank debit order. I have found them to be very efficient at collecting monthly premiums from their members but extremely poor to non-existing service delivery. They granted me approval (authorisation to proceed with requested service) in writing, twice on 2 different occasions, fortunately it’s all in writing (it’s in black and white) so it’s indisputable, but only to go against their own approval. What a shame! How can a corporate organisation issue out a formal approval in writing and only to turn against its own approval unashamedly! I find this to be very unprofessional of any organisation let alone one to which you are religiously paying your monthly contributions without fail. They go into overdrive to request information from you and once you provide them with all the requisite details they just go mum about it despite having given you authorisation to proceed in any case. They thus, never honour their contractual obligations. They issue approvals and negate on them. Very unprofessional this! This is the reason why the staff at Medical Laboratories at Life Fourways told me bluntly in my face that if it’s Affinity Health they never want to deal with them, they don’t pay for claims submitted and therefore they are labelled “bad payer” which is some form of blacklisting of medical insurance and related providers. It’s up there on the walls at Life Fourways - the name Affinity Health unashamedly us displayed up there among a list of other bad payers. I was shocked at the sight of this. I feel cheated! I feel sorry for a whole bunch of innocent monthly paying members who are getting their moneys deducted on a monthly basis but wait until they get to the claims stage - very appalling record on display at major hospitals, almost like no health service provider wants to hear the name “Affinity Health”. What is wrong with this Medical Insurance Company?
