Unauthorised payment taken on closed account

[Donnaneal]

I have had an unauthorised payment taken from my bank account 3 months after closing my account.  I received emails saying I hadnt returned equipment and would be charged but i proved that I had returned the equipment with a receipt of postage.  Unable to connect online as no longer have an account and cannot seem to find a telephone number or email that works.  I have tried replying to the original email several times without success. Can anyone advise

If you are struggling to call them then one other way of contacting Sky is via social media as there are some links at the bottom of this page you can use.
