Do you still have the postal receipt for the items you shipped? You can use it to track your package, and prove it has been received by Telus.
As the Neighbourhood is populated by other customers, we have no ability cancel your bill. You will need to contact Telus directly. I suggest the Chat function at the page bottom, or by reaching them through Twitter at @TELUSSupport.
