That is your other option, phone them up, tell them you are coming to their office at a set date and time.

It's a minefield, the company making the cheque offer is 4 removed for the insurers that I originally made contact with.
Phone them? It's a premium rate number that I stay on for 5-10 mins before getting through to the wrong dept, or, cut off.
They send texts to me to avoid talking direct, the text cannot be replied to, there is a premium number to call...............
They send emails too, these also cannot be replied to but they helpfully include a premium rate number for me to call...........
I am totally jazzed off with it all.
