Dr F Rollands Delay caused me to be handed over.

I am a patient of Dr F Rollands and I had been hospitalized in January at Mulbarton Hospital this year. Due to my doctor (Dr F Rollandss) putting in the incorrect codes for my Lancet blood tests my medical aid has not paid and now I have been handed over to attorneys. I am ill boarded and now I am receiving attorney letters when this was no error of mine. I have been requesting since May for this to be sorted but till now , it has not been rectified, according to my doctor i should have minimal stress, but how can I when the stress is being caused by an clerical error on the doctors side.
