I have been working with technical support for over 3 months to troubleshoot calls dropping in my house. I recorded all the dropped calls as requested. Their solution was to install a network extender, which worked until my network went down. I told them I should not be dependent on an internet connection for my cellular service to work. After all this time, I am going to take the $180 hit for early termination and sell the network extender they gave me to cover the cost of cancellation.
