Wonga don't want their money!

I would like to lay a grievance against wonga. Granted i have owed them money for a while. I am now trying to make contact with this company to settle my outstanding balance but it is next to IMPOSSIBLE! I tried calling their number countless times, sent emails, even got hold of the attorneys I was handed over to only to be advised that my account was taken away from them and they were unable to assist me. They referred me straight back to the same Wonga number I was trying on for 2 weeks straight. It is pathetic that I need to try and try to GIVE money out! Please help HELLO PETER! So frustrated!!
