Audiologist claim rejected for R545.90

Since 27 June I've been trying to get a Audiologist claim processed for R545.90 , keeps rejecting because Speech Therapy which is supposed to fund from PMB funds from day-to-day benefits. Everytime I phone in I'm told they need to re-adjust & correct the day-to-day benefit but for the 3rd time now the claim keeps rejecting because the day-to-day benefit is not updated. I'm at my wits end .
