Bad customer service and no information given

I received a statement from Netcare on the 11th Sept 2021 with no information or reference, I then shortly after received an email saying that I am owed a refund. When I rep**** the person's automated out of office was on and they rep**** several days later.

I was told R2 500.00 and R1 117.40 was paid to Netcare on 10.07.2020,11.07.2020 and 28.08.2020. I questioned how two amounts could be paid over three days but never received an answer. I have no idea what this was spent on at the hospital or what it was for.

It was extremely difficult to get clear feedback and of the two people that were on the emails both of them seemed to always be on leave or have their automated out of office response on.

I was supposed to receive the refund on 15th Oct but never received it.

I eventually received a refund of R913.21 on the 18th Oct but I have no idea if this is the full refund or what I have been refunded for. For all I know I could be owed double this but the refunds department is not supplying me with any information that is valid.
