POOR SERVICE

My husband had to go and have a procedure done on the 17th Feb. We paid cash and sent the claims to Discovery to claim it back. By the 13th March I still had no response from them phoned claim department they tell me that our bank rejected the payment. So I phone our bank and they tell me that they will never reject a payment. I must email discovery again and ask for proof of rejection. And again no response today 24th March phone them again the first person tells me sorry the copy in blurry ask to speak to a supervisor hold on for 20min 53sec no one comes back to me. Phone again speak to someone else she tells me that they payment was rejected again so I ask to speak to a supervisor again hold on from 12min and get cut off. For the amount of money paid on a monthly bases for very very poor service.
