What CMS Credit Monitoring Service are you using?
Have you compared your before and after reports line by line to audit if there is any other changes on your credit report besides the reduced utilization?
I used my 3B's credit reports from annualcreditreport.com for comparison. Don't see anything amiss or exception from last week's report (I am pulling them weekly since last couple of months).
Its a revolving CC with 5k limit.
The score loss was not caused by AZEO.
