Wonga loan

I had a loan with wonga, the 6 months loan, then last month I was called by one of their consultants and they offered me a discount on the current loan i had with wonga,i then asked the consultant that what happens after you guys have debited that amount? She clearly stated that after the amount it will be the last and final debit order and i will no longer owe wonga, fine i then saw that it was a bargain and I should option for the discount, month end came and they deducted their debt order, after 3 days i called one of their consultants to find out if have they received their money and will they then update onto their dashboard that i no longer owe wonga, to my surprise nothing was being updated instead I am still getting messages from wonga that i still owe them, then 7 days later i made another call, and according to the consultant nothing was being updated she then said she will escalate the matter further, but honestly I do not see anything happening because till today i am still receiving texted saying I owe them and i should settle the account

All i want to know from them is that is this how they treat their clients, because it seems like no one is doing their job properly, all i want from them they should just clear my dashboard close my account and give me my paid up letter, i will no longer use their services as they advertise lies
