I HATE WONGA!!!!!!!

I reviewed Wonga previously because of over charging me.I took a loan of R5000 in December 2024.Paid 1900 in January 2025,then paid 2400 in April,they debited 2126 in Feb and Debited 2326 in April so in total I had paid R8568 then I asked for a refund and they refunded me 2162 so now I am getting harassed by Wonga sending me emails and samses that they want to debit.Theor call center even said they won't stop debiting,they don't care if I paid their system is automated to debit me 3 times irregardless of me paying the loan fully they won't account the manual payments,the system will still debit.They even refused to give me a settlement letter,I feel so bul**** and harassed by Wonga.Please help Hello Peter,I am even scared to have money in my account because of them because they even refuse to refund when you alert them its an over charge.
