If its going out when it rains, its likely wiring on your house, not plant. Its probably past the point of demarkation (where you become liable for the line) ... 99% of the time this is the case (ex phone field tech)
You just raised enough attention to make it worthwhile to soak up the cost of replacing YOUR line for you...
Congratulations, you may have joined the ranks of entitled people who use public pressure to whine their way into getting what they want...
