There is £100 in my bank account and I don't know where it came from. Its showing that it was paid in via a branch of my bank yesterday. I searched the sort code and its the branch just down the road from my house, which makes me believe it may not have been an error. Also, you don't need to give sort code/account number to pay in now you just stick your card in the machine dont you? Leaves less room for errors.
I am with Natwest, so it may be something to do with all the errors they have been having on balances etc. What should I do? Tried calling bank but hold time is about two hours.
