Unfortunately no, as we have no contact with the Telecon technicians. Once they're dispatched to the field, even Bell has no contact with them either.
We could do the option of "Due date +1" which essentially would put your installation date for the second tech on Monday (slight possibility of Tuesday)
Personally I'd suggest if it's possible, to leave the appointment for today.
Let me know, and if need be I can have it rescheduled for you.
