When did you send the police report to the CRA's?
OH whats the DOFD on these collections?
And are they Passed SOL?
Since you just sent the police report and info as "not mine" to the CRA's , i would wait 30days to hear from them.
As far as date assigned, if you are talking about a collection account thats the date it was assigned to them, not the DOFD
If you look at your TU or EX CR's it should says date to be removed,count back 7yrs, that would be the DOFD, if reporting correctly.
