Unacceptable service from Wonga !!!!

I'm extremely disappointed with Wonga's handling of my loan account. Despite making timely payments since September last year, my account was submitted to Blake Collections Agency in December without notification. I only found out in February via Blake Collections. They've negatively impacted my credit score, and I'm disputing late payment fees as I received no warnings. Wonga's representative acknowledged internal issues caused the payment reflection delay. I'm requesting immediate removal from collections, credit score correction, and reversal of late fees. Unacceptable service from Wonga!
