********** purchase and bad service

I have logged a dispute for unauthorized purchases that happened on my account sometimes in June and haven’t had feedback as yet from Truworths as promised. When i call in to enquire i’m always told that investigation are still on going and no agent tells me how long it will take for the matter to be resolved. My account is in arrears and this affect my credit record; so since no one seem to know what they are doing, i would like to clear my name and close the account as I wouldn’t want to deal with truworths again. In the more than 10 years i have been a customer, this is the worst experience i have ever had with truworths.
