They sent you notice of cancellation after missing...

They sent you notice of cancellation after missing payment for only 1 statement which I ve never received it at all. Even though I paid full amount on time of the next statement, they charged me for final notice collection fee... After years of being customer, missing one month will make you a delinquent customer and getting charges for late payment plus cancellation notice fee... looks like they don t need customers but customers needs them
