Refund query

I must say that I'm really disgusted with the service I received from KFC Customer Care. I raised a query with them more than a month ago with regards to a refund due to me. On the 5th of February 2022 I placed an order of R136.90 but for some reason it did not pull through to their system, although my account was debited. After contacting Customer Care I was advised to send through a copy of my bank statement reflecting the transaction so that they could refund me as they couldn't see the order on their system. After spending a lot of energy, time, airtime and data, I did exactly that but nothing has been done to date. I have since followed up three times with them but my query just gets ignored. I mean why should I struggle for R136.90 as if I'm fighting for thousands? I must say that I'm very disappointed at the manner at which this matter is being handled. One and a half months awaiting a refund of R136.90 !! That's so ridiculous from KFC!!!
