Leaving plusnet - cancellation not gone through

[#1]

Hi,

We switched providers on 4th March 2021 from Plusnet to Sky so that we could have FTTP (because of our location we couldn't get fibre with Plusnet and the basic broadband is too slow for working from home).

According to Sky, they arrange the cancellation with Plusnet and we don't need to contact to cancel. There has been a ticket/question raised on our account that says 'accont cancellation' so it appears Sky have informed of the service move.

However, we have since received two bills, neither of which looks to be a final bill. Before I phone up, has anyone else had their cancellation take over a month? I don't want to cancel the direct debit as I'm pretty sure we will be due a refund after this latest bill. 

Thank you

Are Sky providing your phone using 'Internet Calling' (VOIP) or the normal copper line ? 

And did they transfer the phone number ?

Hi - yes, we have VoIP, and we were able to keep our original number too.
