Refund

I took a loan with wonga of R1700 in December 2023 and my installment was R813.00 for 3 months. On the 01/03/24 I settled my remaining balance paying with ozow instant payment...but to my surprise I still got debited R813.00 again on the same day. That very same day ..I wrote an email explaining my situation and nobody bothered to respond. I wrote more than 4 emails with no response..and I even wrote several messages on their Facebook page and still got no response. Wonga has a very very poor customer service...they don't care about their customers. Their communication is 0%. Businesses like wonga needs to be shutdown. They are a ****
