Discovery disappoints once again!!!

Good day , I am a medical aid member with ID Number ********** 068087 Medical aid number ********** 60. I submitted a claim on the 24th of November as well as emailed the claim for a gynecologist visit for a refund on an amount of 958 Rand to be paid into my account. The payment date was the 1st of December and when I called discovery after the 5th time to follow up on the payment they informed me that they had the incorrect banking details for this claim, which I find ridiculous based on the fact that no one called me to even follow up on this claim or the account details. Discovery , however has my account details on the system as my debit orders go off on time. To me it seems as if though there is always a delay when discovery needs to repay their members for claims , and we as clients have to utilize our personal funds to call them daily to check on things when there is a refund or claim, but should their be a problem in terms of a debit order on the clients side they will call you immediately to follow up. Discovery certainly has not being providing me with a good customer service.
