Worst loan business to ever use!!!

If there was 0 star I would have given Wonga a 0. It had been more than 3 months that I paid off my account but Wonga still hasn’t updated on transunion and other institutions. My credit profile looks very bad because of Wonga, worst part is that it’s still showing a very high balance as outstanding. How when I’ve paid it off months back???? I am very furious, disappointed and angry at Wonga. I regret the day I did business with them!!!!
