No contact details that we can actually rrach, double debit, **********

I have taken a loan over 3 months and on my last installment I was late with payment, Wonga handed me over to debt collectors without even giving me a call or email, I have arranged payment with the debt collectors and on the day they did debit me what was discussed and as per my debicheck, one day before this could happen wonga has done a debit order, why did you debit my account if you knew you handed me over it was not even a full month it's so unfair on Ppl like us we come to u for loans in difficult times and you hand us over without even a call to arrange a new pmt date, now you have debited me twice the amount from the collectors was more than my installment and I tried calling numerous times I cannot even get a hold of you guys, you need to repay me back the debit order that you have taken, what kind of system do u have that you can't even cancel a debit order on ur side, you just want to **********ly take our money and not give a correct contact number, if push comes to shove I will reverse that money you took from me, this was my last installment, please give me a proper contact number, I will never again use ur services and I certainly do not recommend anyone to use.
