More install issues

I have had 3 visits for final connection all where they have presumed the route to the property was completed as per the first guy who visited instructions.

No civils work has been done.

I was then contacted by email from the guy incharge of the civils explaining everything was

“Locked in” and we would be sorted Wednesday next week, today I get another email from the same guy saying it is Friday to sort it.

I replied saying he’d already booked Wednesday and I was booked off work to be there.

His response was to say there was no such email sent.

I really do not know what to do any more.
