Poor customer service and assistance

I have never experienced any pronlems with Wonga. I took a loan but could not repay. I called Wonga on the 9th of May. Spoke to somebody and they advised me that a consultant from the repayment department will call back. I received the call and they then made an arrangement with me to repay the loan in 6 instalments...she also advisede that she can only make an arrangement for two months at a time...i got an sms two days ago, stating that Wonga will deduct the momey. When I called Wonga yesterday, NOBODY could assist me. The one lady said she can only suggest that I withdraw the money...to make sure the d/o dont run....I told her that I made an arrangement...she then said she will get aomeone to calle back im the next hour.... I am still waiting for the call.... The whole loan amount has been deducted.....and I got an sms this morning again....stating that yje money will be deducted....so, why was the loan amoumt taken, if according to the sms from this morning, imdicates that I have am arrangement..... Very disgusted...i dod my part to make an arrangement, but seems like Wonga doesn't worry about their clients....
