Does Customer Service communicate with Accounts?

I cancelled my club membership with Edgars, as I am now a pensioner and am cutting back on unnecessary expenses. Their customer service department was very helpful and agreed to the cancellation, which was done in May. However, I later received a call saying that they had already printed the statements, so i would have to pay this month's, which I received by email this morning. This means they may have printed it, but they had not mailed them to their customers at that stage. I do not feel obliged to pay the amount, as they had cancelled everything when I called them.
