No Delivery on my investigation against *****

I lodged a request to investigate a ***** case against my name in September 2015 and up until now 8 February 2016 this matter has not been finalised. I am not willing to accept that this case can take such a long period to investigate or finalise. I have waited long enough and have made enough phone calls to Woolworths Head office to get this finalized. The response from Woolworths is that they are still waiting for documentation from the store where the ***** occurred. I really do not think it takes such a long period to get documentation from their own stores to solve this matter once and for all. This ********** account still remains on my name and tarnishes my name. Please help!!!!
