Complaint about my refund

I have a complaint against Ford Credit, in March 2023 I received about 3 SMSs from Ford stating that after a review on my account an amount of R198.82 is due to me because they continued charging interest on value added products on my vehicle when it went on arrears and I was given a number to contact to provide banking details for that refund, I called the number provided and the lady I spoke to advised that it's not her dept dealing with these refunds and that I should send an email with a copy of my ID for them to forward it to the correct depart.

on the 25th of March 2023 I sent the email and received feedback from a Greg Klaaste that the request was forwarded to their admin team that will get back to me, I did not receive any feedback from that admin team until I followed up again on the 25/04/2023 a month later and advised the same as before by the same person that my request will be forwarded to the admin team and I highlighted to him(Greg Klaaste) that he said the same thing a month back and I never received any feedback from him sadly up to date I have received any feedback from Ford Credit.

The frustration is that they send us SMSs telling us that they have to refund us now where is the problem in refunding a mere R198.82 that I have to follow up so many times with the company when you initially sent me the text messages of the refund now why not process it and be done that it should take almost 3 months following up, your service is so disappointing.
