Bad Service

I dont know why it is a problem when drs bills are paid previously and then when it is submitted again it is rejected.I have contacted Discovery and the dr has contacted Discovery and spoke to Nicole, Kamo and Mikkela on the 29/7/15, 3/8/15.Reference nrs *** and ***.The people in your claims department seems to be illiterate and should be send for reading classes.I am sick and tired of explaining the same thing over and over again.I have spoken to the drs and they also have contacted Discovery with the required information.What do you want me to spell it out!!!!!Last year you paid this chronic tests out of the chronic benefits now it is a problem.
