Unresolved payments issue

I am extremely disappointed with Wonga. I have been settling my loan amounts on time, often paying early, yet Wonga continues to debit the same amounts from my account again. I have sent multiple emails with proof of payments and proof of debit orders, but they have not responded or resolved the issue. This lack of communication and failure to acknowledge clear evidence of payments is unacceptable. I expected better customer service and prompt resolution, but instead, I am left chasing my own money. I would caution anyone considering using Wonga to be aware of these issues.
