Get your mother in law to cut it, or ex-wife. Maybe take out a quick life insurance policy on them first. Just in case something "tragic" happens .
Give them a call. I bet they show up before the end of the year.
Yes you can cut it. I cut mine as well when I no longer used phone cable as it hung lower than the others and was bothering me. Just cut it and laid it next to the pole. Telephone is low voltage. Good way to know is by the size of the wire. There are 10 to 16 strands of very small diameter wire in that cable wrap. All low voltage.
