Lancet refund bank statement required.

My Dr. requested some tests to be done and I contracted Lancet Laboratories to do the necessary analysis and submit a report to the Dr. After the results were submitted to the Dr, Lancet contacted me by stating that my medical aid did not honor the payment, and the outstanding amount should be paid by me. I requested Lancet to provide me with a statement. Upon receipt of which the payments were made.

Later on, I got a notification that I will get a refund and further stated that " kindly forward proof of payments reflecting on a bank statement dated **** showing account holders details, this is per audit requirement as your refund is above R5000.00".

I submitted the proof of payment but they insisted on me submitting the bank statement. I strongly believe that it is ******* for them to request my bank statement as proof of payments were submitted to them.
