Centurion Decofurn won’t give me a refund

I bought a headboard on the 1st of November and returned it on the 3rd of November for a refund. I completed forms with my banking details and emailed them to a manager Iwan Kleynhans, nothing has happened ever since. Nobody has informed me of anything and that’s the worse part. I have called the branch for an update Buhle told me that the manager would call me back. I emailed him and he said he would call me back in 30 minutes and he never did. This is terrible customer service from Decofurn and the refund in question is such a small amount. That I’m grateful for because for all the other furniture that I was yet to purchase from them, I won’t make that mistake again.
