Hi. Our Verizon landline rings almost constantly throughout the day. Either no one is there when we answer or it's a telemarketing call, live or recorded. We've blocked many of the ones that use the same number each time but usually the number varies, which makes blocking difficult. The calls start early in the morning, often waking us, and continue late into the evening. We'll sometimes get thirty or forty calls a day and it is driving us crazy. We're on the Do Not Call Registry but that doesn't seem to make a difference.
I would appreciate any helpful suggestions.
