The number on my caller id was117207534536-that's too many numbers.And caller id said "invalid number".So I didn't pick up because I thought it may be the annoying " IRS guy" calling for a hundredth time.
Since we have a very helpful blocking assistance company that we use this number only rang once. If, as other callers have mentioned, they continue to call, we'll put them on our phone companies blocked caller list by entering their phone number. For those callers who continue to receive harassing phone calls check online in your area as there are wonderful companies out there who will help you block these calls or at least it will only ring once and we are so grateful to have this company. It will be worth your effort and time to look into these companies so you can have peace during the day, peace at supper time, and sleep better during the night.
