Hello,
thanks for using the forums to get this issue sorted. I can see you're wanting to cancel your services with us. We wouldn't be able to help on here as we don't have the systems on the forums. However if you call 0345 454 1111 and choose options 1, 4 then 4 again you will get through to the cancellations team. They will be able to help get things wrapped up for you.
Thanks,
Megan_L
