Terrible service from wonga

Terrible customer service in that they never respond to emails and if they eventually do then it's a generic response. They also fail to update your loan status but are quick to take your money. I app**** for a loan last month and paid the money back in full on the date that it was due and it's still showing that I owe them money. It's been almost 3 weeks since payment was made and it is still showing with the credit bureau that the loan is outstanding which is impacing me negatively. I've contacted wonga on numerous occasions regarding the matter and still no response or resolution. This is pathetic service from such a big company. I am truly disappointed and want this resolved immediately
