Hi. I have had major, though intermittent, connection problems: dns server not responding. I tried to book an engineer by phone but got cut off while waiting. I tried to book on the net, only to be told 'link expired'. I have tried many times this week. Could you please arrange a booking with an engineer for me? I need the connection for my work (in the health sector - people's welfare depends on it). Could this be treated as a matter of urgency? Thank you.
