Barclays Credit Card Complaint

Barclays Credit card department,

APR or interest rate North Carolina

I was offered a - ( now - - - card in about - with 0 % interest and $4000.00 credit line while flying back from seeing my granddaughter in DC. This was heavily pushed by flight attendants. I applied and used it judiciously. Since that time they have raised the card from the introductory rate of 0 % to $24.00 ( Variable ) reducing my limit without notifying me, and are charging an impossible $68.00. monthly interest. They reduced my limit in - and charged me an over limit fee when I did'nt know it was reduced. I HAVE NEVER BEEN LATE ON PAYING THIS ACCOUNT. I have paid large payments on more than - occasion. This credit practice creates the kind of consumer cycle of debt which nobody can get out of and occurs after a " bait and switch ' marketing approach. I am a senior, self supporting, work fulltime and pay bills on time. This is exactly the kind of credit practice - can help intervene on. THANK YOU
