We have had this credit card for over 5 years with a sizable credit limit.  Today we received an email from the Credit Card Company-Barclays Bank of Delaware...US Airways Dividend...they lowered our credit limit due to us paying off our monthly charges when the statement was due. No one in customer service could tell us why we were cut from the high limit to down to $1500.00.  The one associate told us we never charged over $2,000.00 in a month.  So why did they cut us down to a credit limit of just $1500.00 when we spend about $2,000.00 per month.  We pay our credit card every month in full....
