I did of sorts. They suggested that I ring Tesco bank. Which I did today. They have said the signed documents have still not arrived with them(I sent them two weeks ago). They suggest that I phone in on Tuesday at 2pm to see if they have arrived. If not they will issue me with a separate set of documents , which I will need to sign and post immediately. In addition I will need to phone them to say I am posting these, can they be sent to the underwriters as a matter of urgency (the deadline for the loan agreement fast approaching!).
As you can see, a fairly comprehensive answer. I just dont understand what happened to them? Anyway not Tesco's fault, more likely Royal Mail. So we will see.
Thank you for following up with me.
