Handed Over to Debt Collectors for paid fees

On 15 December 2024, I was admitted to NetCare Linmed Hospital for acute allergic reaction. Apon arrival, my emergency contact was informed that I would not be treated by the doctor if payment was not made. She paid R1700 for Hospital fees as billed by Netcare Linmed and R1020 for Doctor’s fees. On 23 December 2024 I received an sms stating I have an outstanding fee of R2741,90 that needs to be paid for Hospital fees. On 27 December I sent an email to Netcare’s customer service email detailing everything that was said to me on the day of admission as well as my proof of payment, I was emailed back the following automated response:

Thank you for contacting Netcare.

Your enquiry has been logged with reference number NTC***.

Kind regards, Netcare

I had not received any feedback and called back on 30 December but my call was cut. Now I have been handed over to Saya Recoveries Debt Collections even though I have paid my fees upon admission and have reached out on my end to sort out the query. This is highly unprofessional and ********* that you have handed me over to debt collectors even though I have reached out to you guys to sort this out and still no response has been given on your end, only debt collectors sent my way as if though I have not paid.
