Wonga Customer Care SUCKS

I have lent from Wonga a few times and they really helped us in time of need, but this time I am truely dissapointed. We fully paid my account in December 2023 (which is 2 to 3 months ahead of time), sent them the notification, as well as my bank and OZOW cleared the payment BUT after that, they also took the debit order for December although it states on the portal that I owe nothing - they do not respond to one email when contacting them (we have sent them 13 emails so far) as well as no response when calling their customer care line (which I have called 5 times). They are quick to call you when payment is late, but they do not have a care in the world when they are in the wrong and owe YOU money.
