Cancel contract

[Eva73]

Hi, What is the land postal address to write to O2 to cancel my contract? I do not want to transfer to another provider and I do not want to keep the number. The original SIM cards have been lost. I've tried the help number, and once I finally got through, they could not do it. Thank You.
