BAD SERVICE

I am so angry right now. I took my baby to the specialist on the 17th June as he was very sick and I couldn't go to the GP first for the referral letter so I paid cash hoping i will claim later. I sent through an invoice from the dr to claim but for some reason the money went to the dr i called on the 2nd of july trying to rectify that and asked how did it happen the lady who was helping me Sibusiso said she doesn't know why they did the she log a query for me to get it reversed and paid to me. On the 04th of July I called again to do a follow up I was told i wont be paid cos i had sent tax invoice from the dr and not the receipt, i asked what was needed to sort this out I was told to send the receipt I received when I was paying at the dr I did. Today 09/07/2019 I see an email coming through they had yet again paid the dr and not me, I call them again to be told that my receipt does not have a stamp from the dr and it does not state that I paid the dr. For crying in a bucket THE RECEIPT HAS THE AMOUNT I PAID, DESCRIPTION OF WHY I WAS PAYING,CHARGED TO WHO ,RECEIVED BY THERES DR'S SIGNATURE AND APPROVED BY THE DR AS WELL...THEY EVEN ADDED THE CONTACT NUMBER SHOULD THERE BE A PROBLEM PLUS THERE IS HIS PRACTICE NUMBER. I am cancelling this medical aid DISCOVERY KEYCARE PLUS I don't get what I pay for and there is too many red tapes!!!!
