Identity theft

I had my identity ****** soon after I had visited a dealership and submitted my documents to Westbank for VF a few weeks ago. I was alerted by my private banker of this ********** act. They had gone to an extent of applying for "my driver's " licence too and they were in a process of buying a car worth 1.6M. I am now told that Westbank refused to investigate. Now, on what grounds are they refusing to investigate? I deserve to know who did this. I am pretty mush sure it was an inside job and I demand to know who did it!!! It is my right to know. Not that I will ever again use Webank for any of my financial needs but the public also deserves to know that Westbank doesn't care of potential clients!!!
