LIfe - You need Respect as a company value

My daughter was at Life Suikerbosrand week of 11 May 2020. Visit/Reference number 209096 I had to pay a co-payment of R5 000, and I was told that when the medical aid pays the account, the balance will be refunded to me. Total value of the claim was R11 384.04 Discovery paid R7 286.25 Therefore, Life owes me R902.24 I have sent mails to Frieda Daschner (Patient Services), Angelique Olwage (Hospital Secretary) and Lebo Tlaka (Reception Supervisor). Not once or twice, but numerously, and they don't even respond. I am just being ignored. This is now over a month and a half since she was there. I have sent a message on the Customer services page of the Life Healthcare group, also no answer. I am just being ignored. If I did not pay that money, you would not have provided the service. But I have to ask for a month and a half when I am going to get my refund? What else do I have to do to at least get the respect as a customer to get a response on when I will get my money? Is that how much respect you have for your customers, that you will not even take the courtesy to respond to your customer? Do I have to lodge a case of theft at the Police station? I would have thought that a corporate company like yourselves will pride yourselves in the service you provide to your customers, which include at the least, responding to your customer when they ask you a question, and secondly, returning the money that you owe them.
