I took a loan with Wonga December 2020 and the was a miss communication with regards to my debit in December, I got a call from Wonga to settle the whole amount of R1200 which was collected successfully on the 25/02/2021 ,few days later I get a call from Wonga saying I owe them R97 or more I don't remember clearly, I tell the agent I made an arrangement to settle the whole amount and what is this amount for she couldn't even explain. today I checked my credit score and it shows I owe Wonga that amount , I want Wonga to remove that amount as it's not my fault that they don't now what their doing , they trying to crock me in to paying what they failled to explain and it seems like they don't no the meaning of settlement.they need to get better agents who now's how to talk and explain to us properly.
