Bad service!!

On 7th December I went to the Doctor after calling Flexicare to make sure it was all above board and covered. They told me it was covered. I tested positive for covid and the claim was rejected. I called again and they asked for the lab results, which I emailed through immediately. Now the claim has been rejected again, I called but sadly ran out of airtime. The consultant I was talking to was laughing in the backround whilst I was explaining my situation. She proceeded to tell me that the wrong lab was used. I asked if I was in a position to tell the Doctor what to do. I was cut off so I did not get the latest excuse from Flexicare as to why the claim has not been covered. Sadly, Flexicare gives you one story after another in order to NOT cover your claims. They are absolutely useless when it comes to giving a member information, not to mention service. This of course is non existent..
