The participants in the Neighbourhood are almost entirely customers of Telus, and unable to offer that form of support. I suggest connecting Telus through their Facebook or Twitter accounts. You can find other means in the 'Contact Us' section at the page bottom.
BTW, needing a PUK code is a separate issue from the unlocking situation. Be sure to explain each issue separately, as the PUK code is associated with the SIM card, and the unlock code is associated with the phone firmware.
