Chase Credit Cards ripoff cut my available credit by over 50% and I've never been late once! Wilmington Delaware

I just received 2 letters from Chase Card Member Services. 2 of my credit cards have had their credit reduced by over 50%. I have never been late on any payments. They even increased my available credit just last year. My credit score is right around 700. One of the credit cards I recently paid off. I have spoken with several supervisors and they all tell me they can't help me. I use my cards for business inventories etc. and I switch them around so I can get low interest rates. Because of this reduction my credit score will drop because it will lower my ratio. What a rip off! Who treats good customers in this manner? I can't wait to get rid of these cards and never do business with Chase again.
