Netcare not refunding my co-payment , and delete mail without reading them.

I was admitted to Linmed Hospital on 24th March for a procedure and was advised I had to pay a co-payment. As this is part of my cancer treatment, the medical aid was approached to waive the co-payment, to which they agreed. Since I had already paid, I requested a credit from Netcare. The email and supporting documents were submitted on 25th April 2025. On 7th May 2025, I sent an email requesting confirmation as to when my refund would be processed. On 8th May 2025, I received an email stating that all my documents were received, but there was no mention of the refund timeline. I rep****, seeking an answer to my initial query and clarification on why the confirmation email was delayed by two weeks. Unfortunately, the email I sent was deleted without being read minutes after sending it. It appears that Ms. Nonhlanhla Kubheka may not be fully committed to client service and perhaps should be reassigned. As a pensioner, R7200 is a significant amount and cannot be overlooked. If you review your records, you will find a similar complaint from me regarding a past refund request. Is it Netcare's policy to delay credits? It certainly seems to be the case. I have copies of all emails date and time stamped should you require further proof.
