Poor customer service and administration

I have been trying to close an account with Mobicred for the past 6 months with no success. Have made dozen of call to the call center with consultants always promising to call me back but never do. I have a paid up letter from the same company but somehow still get bills at the end of the month. Unfortunately they are still providing credit bureaus with outdated information which is adversely impacting my credit profile. I have no choice but to seek relief from the Credit Ombudsman.
