Very very disappointed with Discovery Claims Department

Claim number ********** 373, im so disappointed with Discovery health, my son was admitted to hospital on the 20/09/2018, instead of Discovery paying them from my hospital benefits they paid from my medical savings, i paid two doctors and the hospital and i claimed from Discovery, claiming has been a nightmare, instead of refunding me they pay the health professionals, i have attached all the proof of payment but still they don't refund me,i spoke to Thabile today the 31/12/2018 reference ********** 782 & she confirmed that they have received my proof of payment but they still made payment to the health professional ,i don't trust discovery anymore how can they repeat the same mistake twice really i have been patient but now i want the money to be deposited into my account, i was told by one of the employees thar they don't read the body of the email hence they make such unnecessary mistakes, Trish from Durban confirmed that everything was sorted but I guess she was lying, discovery must do something about their claims department because they are always messing up, 1 day a huge amount will be paid into the wrong account and that is when Discovery will wake up, i don't understand how such a big organisation can make such petty and stupid mistakes
