Capital One Credit Card Complaint

Capital One Credit card department,

Credit line increase/decrease Pennsylvania

Capital One randomly and without my consent to reject ; has increased my credit limit three times in the last year. These have been significant credit line increases. Capital One says because of my good standing, they increase my limit. However, they refuse to lower my interest rate. I have a high interest rate and Cap One keep raising the credit line to potentially extract more money from me. It seems this practice is unethical at best, because if I 'm such a good customer, then lowering my rate would be the best practice. I contact the - about this and Capital One replied w/ a scripted response. Capital One is practicing in unethical practices by not allowing the customer to decline a credit line increase and they say " accounts are periodically reviewed for credit line increases '', but say my account is n't eligible at this time for an APR reduction? Makes no sense. If I 'm such a good customer, then trying to squeeze more money from me on a high interest rate from credit line increases is very much a sleazy tactic.
