good evening kaydee,
I have just rang the 020 7087 4600 number and within 1 ring it was answered. The lady offered to put me through to the contact centre. I did ask for an alternative number but she would not give me one.
I would suggest if you are a customer of PhotoBox they can also be e-mailed with any feedback
here As the 020 7087 number works it may also be worth trying other numbers after that to see if any connect to the menu used for the 0844 number.
I will in the mean time look at the numbers shown.
I hope this helps.
