Shocking service from discovery medical aid

Went to see the doctor was in a gap, so they had to pay me direct and not the service provider, the first time I submitted a claim it was rejected, they said the doctors practice no was not there, we resent it, we were than told the code was wrong, for the claim, we te submitted they than returned it saying that the procedure code and another code were below each other, and the numbers must be next to each other, nobody from discovery had the decency, to contact the service provider, and tell them what they needed, maybe they are too big now and can't be bothered, we are talking about 650 rand.
