ITC - Without submitting the correct ICD 10 Codes

Me & my husband had our annual bloodtests done at Ampath in Nigel. The sister forwarded the paperwork, and my husband`s account was paid by Gems, but mine rejected because the wrong ICD10 Codes were submitted. I have exactly the same codes as my husband, and his were paid but not mine. <br> We called the sister in Nigel and she submitted the wrong codes (I hope the blood was mine). We called her to fix it, and we`ve called the main lab. We`ve also send them an email with all the correct codes. It was still not fixed. I went back to Nigel, and she said I just have to start paying off. This is all PMB conditions and will be paid by the medical aid if submitted correctly!<br> The non-payment of the account was due to Ampath`s mistake, and now they blacklisted me! I want this matter sorted out as this was due to bad service! A letter of apology and a clearance from ITC is expected!
