Sky cancelled, equipment returned and it showing a further 3 estimated bills for tv essentials only

I cancelled my sky the month it was due to come to an end of its contract. I sent equipment back, I went on to check my account and it's showing as credit due but taking off next bill which I was told I would only Pay what I used in the time I had left of contract which was like 12 days.

It is also showing 3 future estimated bills for tv essential, I'm unsure why if the contract has come to an end or is it still to be updated whilst waiting on return of equipment.

@mvmbvmn  As you need to give 31 days notice how did you do this?  Did you receive confirmation of the cancellation?  Send equipment back doesn't automatically end your TV subs.

I was on live chat speaking to a sky expert and yes I got a cancellation email.

It might be worth calling them so they can check that your account is actually now closed.
