CL's not replying yo emails

I recently emailed a CL close to the NEC with a query about a pitch for the show in October, to date I have not had the courtesy of a reply.

Even if the CL was fully booked for the dates we wanted it would have been courteous to email and tell us.

I would have phoned, the mumber was a mobile, we get free calls to landlines but not to mobiles.....I do have a PAYG mobile which is used only for emergencies, emailed instead.
