took £43.03 out of my bank account after I canceled my sim card and still not payed back
Thanks for your post and welcome to our community.
Sorry to hear that we've taken some money out of your account after you cancelled, I can appreciate you're keen to get this sorted.
When you cancel we take 30 days notice, within that period your final bill will be produced. Is it possible this is your final bill?
I'm happy to have a closer look if you'd like, just reply to the personal message I'm sending you and we'll take things from there.
