My first AIBU and I most probably am, BUT I am a woman on the edge.
Basically our phone and internet were cut off 21 days ago by another utility company. When they backfilled the hole our services ceased to work. For the whole street save for one house. The guys who did this were approached by my DH and they denied all responsibility and schlepped off.
Ok cut a loooong and very boring story short and despite numerous complaints to all our service providers BT Openreach continue to lie to us. We have had so many dates of completion that have been and sailed past with no resolution in sight. And they will not talk to anyone who is not a BT customer. I have had a snotty email from them telling me I am not allowed to talk to them. . And the buttmunchers have told us that we would have 10 engineer here to fix the problem today 
So am I BU unreasonable to hatch a plot to ambush the next engineer who wanders into our street and hold him ransom until our job is fixed. And if I take this course of action am I also allowed to demand a takeaway pizza, 1 million dollars and a helicopter to take me to a tropical island as in all good hostage movies?
