Claim still not reprocessed

On the 22nd December, Michaela from discovery phoned me regarding a claim that was incorrectly processed by the claims department and advised me that she had spoken to the claims department and that my claim would be reprocessed... she then indicated that she would be in touch with me today 27/12/2017, however no one has contacted me from discovery and my claim is still not reprocessed... I am tired of discovery giving me the run around... I submitted all the required documentation... I was promised that my query would be resolved by now.... I want my query to be resolved now... I am tired of being nice and accepting this disgusting service.... this is a radiology claim which was incorrectly processed by the claims department as no procedure code-michaela confirmed that the tariff/procedure code is on the claim so what’s with the run around...
