Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Florida

Barclay Bank Barclaycard, I went online to review my account and discovered my credit limit was reduced from $2000.00 to $1200.00 without any notification from Barclay Bank! I called them and they said because of credit usage on other cards NOT Barclaycard that they reduced my credit line because of that. I spoke to one of their credit representatives at Barclay Bank and did not get any positive response from her ( - ). My account with Barclay Bank has always been paid on time and more than the minimum payment due! All my other credit accounts are always paid on time and with NO derogatory information on my credit reports! This practice of reducing ones credit limit for NO reason should be illegal and furthermore the bank NOT notifying the person of the reduction is WRONG! With Barclay Banks action this now may effect my credit score because with the reduction my balance is now 75 % of my credit usage on this credit card! I am - and have NEVER had a credit limit reduced from any credit card company!
