Bad customer service.

On Friday that was 0/26/2024 I made an immediate payment to settle my loan, I used the correct account details and reference number however, the payment is still not allocated and what is worse is that Wonga tried debiting my account for the same amount I paid. On my account it now shows that I have a failed payment simply because they failed to play their part and allocate that amount I paid. Their customer service is a joke, I have been sending emails and I get no responses, what is worse is that their customer service number goes straight to their useless IVR system. I am so disappointed and angry with their poor customer service support, and their ****ming tendencies.
