Having getting calling Verizon as well as emailing for almost a month. Phones are not the problem they all are having the same problems at the same time (3 phones). Verizon tells us they have checked network and no problems. This is can not be true. Phone is used for my business as primary number. I must have reliable service. I have been a customer of Verizon for over 30 years and never missed a bill payment. Please help.
