Not paying my refund since 2022 - No feedback, Lack of service and extremely Poor communications

My daughter had an injury dating back to 28/12/2021. I paid for the medical services as my savings was depleted with Discovery, however, it was an emergency and I claimed back from PMB. Discovery paid ER Consulting in April 2022. I only was notified by ER Consulting in May 2024 regarding the credit that is due to me. I then contacted the company on the 28th of May 2024. A consultant advised that I must email my ID, Bank account details and receipt of the payment made. I emailed the information to *** as requested on 28/05/2024. I received no feedback on the refund, so I contacted the company and spoke to a Reneilwe Ragolane on the 14th of June 2024. She was not very polite when I questioned the reason for no feedback and that my refund was not paid as yet. She advised that the initial consultant did not advise that I need to also complete a refund letter. This was frustrating to be advised of this refund letter. Reneilwe emailed me the form on the 14/06/2024 @ 9:38 am. I signed and emailed back to her on the same day @10:34. She advised me to email her asap as they do refund each Friday. To date, I have had no feedback nor has my refund being paid. I sent a follow up email to Reneilwe on the 26/06/2024 and no feedback still. I see that she works for a company called Firstcare Solutions (assume a billing company) based in Sandton. I tried checking details on their website but it’s under repairs. The refund due is R1801.70. I need someone to urgently advise. Discovery paid your company, and that money is due to me. Why is your company holding back on the refund. I will also be in contact with my medical aid Discovery to inform them of this and to advise me on the way forward should I get no feedback.
