Refusal to pay refund

On the 12th of August 2022, I accidentally transacted for a software product online with the incorrect bank card. I immediately informed POWERLINE GROUP of this and told them that I had not even used the product due to the mistake done using my bank card. I was promised a refund more than a month ago and to date, I have not received my refund. They keep on promising that they will refund me, but it hasn't been done. they say they are escalating the matter but still, nothing has happened. I would like to get help regarding this matter, in any way that I can as I still need , my refund.

Hoping for a response with assistance.

Kind regards Ms. Unathi Ntshuntshe email: *** +***
