Barclays Bank Delaware review: Worst creditor ever!

I often have a running balance on my card. Only recently, I have had this creditor drop my credit limit without notice, or warning, despite NEVER having missed a payment, nor have I ever been late! I often make larger payments than required. As soon as I get a couple thousand paid down on my card they drop my limit to what I owe. They have done this three times with a lame excuse as to why. They beyond suck! I hope their company goes under. They don't deserve decent customers when they treat us like this.
