unresolved ***** account

discovered that an Avon account was opened in my name when I went to the bank as I requested for a credit report, I am now black listed due to this ***** account, I have contacted the Avon credit control department which they requested for documentation and I have sent them the documentation they requested for the investigation to date I am still awaiting a response from them and I need them to clear my name off the credit list, as I know they have all the documentation they requested from me why is it taking them so long to clear my name and with the investigation , this investigation should not take them long as everything they need is there I submitted the required documents , all I want is my name cleared so I can continue with my life coz its currently stuck /on hold because of the ***** account...
