MSA Depleted - But no Invoices sent to me to pay

My savings ran out middle of the year 2017. In November both my kids had to go to hospital for dislocated elbow and 3rd degree burns whilst on holiday, then follow up visits when we got back home. So various places we had to go to. I have only received 1 invoice to pay from wherever we were those visits. Discovery has rejected to pay because my savings has been depleted. I asked them okay, if you not going to pay it fine. But please send me the invoices submitted for payment, so i can pay it because these places have obviously submitted it to Discovery and not to me personally. Discovery can't help me. So what do I do now!? I can't pay my accounts even though I want to, because my medical aid who the claims were submitted to, can't find the invoices submitted to them for payment, and fwd them to me so I can pay,. It's really. The MOST ridiculous thing I have ever heard in my life. Now I have to sit and wait for final warnings to reach me before I know where I must pay. Pathetic service, I am still dumbfounded as to how this is even possible. It's a joke. I wish my company didn't force us to use Discovery. I was actually very happy with Essential Med. Never had to pay in. Unlimited GP and Dental care etc. No stupid medical savings that 'runs out' Customer service excellent even though you pay alot less. It's a pity EM is not a full medical aid. Discovery is pathetic.
