Unacceptable lack of communication

Good Afternoon, I am a registered Debt Counsellor who has been trying to contact your call centre for the past two months. No one answers the phone. I have also sent emails to two email addresses listed on the Wonga Finance webpage, and have received no response. This lack of response on the part of Wonga Finance is making it impossible to issue a Clearance Certificate to my client and to finalize her debt review. If this lack of response and non-co-operation continues, I will have no option but to seek legal advice.
