Zero response from FNB Business ***** Department

I placed an order with a company named Rentoza on the 13th of December,they declined my order in the 17th aftwr I followed up with them several times due to no communication from their side aftwr they had taken my money.

According to this company's e-mail they sent to me on the 17th of December, I should have received my refund on the 8th of January latest if I count their 6 to 12 working days they communicated. They have been ignoring me and now I also feel like my own bank is ignoring me.

I have not received any calls from you, when I go on the app it shows I have no open incident reports with you.

I raised this dispute with you on the 27th of December and I have not heard anything back.

Can someone from FNB Business ***** call me urgently, I am not sure what to do because the company Rentoza is not responding neither is FNB.

I am not happy with your service at all FNB ***** department.
