I phoned the office having just moved out of a rented flat with Belvoir with the hope that they could pass on my details to the current tenants, as some very important post was to be delivered which I could not change the address for. Whilst I now understand this is not something that should be asked of new tenants, I found the advisor to be very rude and unhelpful in this situation. It may not be possible to complete a task for a customer, but you should at least address them with a polite manner.
