Chronic doctor not paid

Visited the chronic doctor in September and submitted the claim. Was informed the code was incorrect so claim was not paid. Revisited the doctor in October where code was altered and submitted both claims. Claim was rejected and was said there were no funds in the savings. We never had a problem claiming from this doctor before so I phoned them and was informed that there were three doctors visits under chronic available. They then resubmitted the claim and yet again received another email stating it will not be paid as there are no savings available. Please this chronic not savings and all codes are correct according to the chronic department.
