BBVA Compass Clear Points Had a BBVA Compass Credit card with a $12,000 limit and it's been lowered to $2,500 without cause Birmingham Alabama

I recently possessed a BBVA Compass Clear Points credit card and unknown to me, BBVA contacted TransUnion credit bureau who told them I was overextended.  I'm not.  I have plenty of assets to live on and no one checked into that before making this determination.  I have contacted BBVA Compass and they "said" they believed I was treated unfairly by TransUnion; however, they stuck with their decision to lower my credit limit from $12,000 to $2,500 without my knowledge.  I found this out when I went to pay a $30 airport parking bill and this card was declined. 

Since it was over Memorial Day weekend, I had to wait until Tuesday, May 29th to inquire about what happened.  They informed me that TransUnion sent them a notification that I was over extended. When I contacted TransUnion, they disavowed any knowledge of having done so.  This all came as the result of investing in a real estate class to the tune of about $50,000.  I have NEVER been late, nor have I ever contacted a credit repair service regarding this issue.  BBBA is treating me like an irresponsible criminal who doesn't pay their bills.  They had no right to do what they did to me.
