Like you suggested a short lease for a certain contract, but due to the telly programme sucess who knows?
A pity you haven’t had a reply, publictiy is good, depends on the company.
That said I wonder how many emails they get after the telly programmes?
I would have look at emails that that could generate income for the business rather than general questions if I was them.
They are running a business after all so hang in there:)
