I am writing to formally raise a complaint regarding an unresolved issue with a device purchased from Three.
I am unable to obtain a copy of my invoice, as I have been repeatedly informed by your customer service team that it cannot be located in your system. As a result, I am also unable to obtain a proof of purchase, which is required for an active insurance claim.
Additionally, I have been advised that, due to the absence of the invoice, you are unable to provide a proof of usage confirming that the device was registered and actively used on your network. This document is also essential for my insurance claim.
I have spent a significant amount of time contacting customer support via chat, but unfortunately no resolution or alternative solution has been provided.
I respectfully request that this matter be escalated and properly investigated. Specifically, I require
A copy of the original invoice, or a valid alternative proof of purchase
An official proof of usage confirming that the device was registered and used on your network.
These documents are urgently needed to proceed with my insurance claim.
I would appreciate a prompt and clear resolution to this matter.
