Discovery not paying claims on time

We are retired people , sent claims we paid to be processed , this was not processed reason being the dates were not clear. We had to go to the local print shop paid them to print and scan clear copies. These copies were sent to Discovery ten days ago and they just ignored our mail . When i called today they again said its not clear. Consult Candice checks and sees the copies are clear and only today she sent the claim to be processed. This service was in July. This is unacceptable
