**PLEASE READ THIS**
I’ve been trying to retrieve my supporting documentation I.e my other nationality passport and after several phone calls and hours waiting I managed to have my call transferred to the senior team. One advisor advised me to try to go to Corby in person so I can speak to someone and retrieve my passport so I can travel next week. I was also informed by this advisor that he would write an internal note, advising the team I would go there, since he was unable to transfer the call directly or provide any other contact.
I went all the way from London to Corby (to the postcode confirmed by the advisor, who also confirmed my documents were still there) only to get into an industrial park, which basically processes the documents and played oblivious to HMPO and having no idea what I was taking about. I ended up going to the sorting centre in Corby to find out the correct address, hoping that was a misunderstanding and there was indeed another building and someone aware of my visit.
Apparently I was one of the few people being misinformed, the staff at Corbys Royal Mail sorting centre reported several people turning up with the same problem.
So if anyone advises you to do so, don’t do it as it’s a waste of time and money
