How to stop Vodafone from sending me bills after my contract has ended?

My iPhone 4 pay monthly contract should have ended a few months ago, but I keep receiving bills from Vodafone, is there some way of cancelling this permanently?

You should have phoned up near the end of your contract and say you don't want tp carry on. But dunno what you do now. Just phone up I guess

You have to call them to cancel service. After your contract ends it doesn't automatically cancel, you just become a month to month customer.
