Hi there! My name is***** am a computer professional with over 15 years of experience with both Mac and Windows. I'm sorry that you're having this issue. It would be my pleasure to help you resolve this. Let's try this please. Unplug the base unit’s AC adaptor to reset the unit. Reconnect the adaptor and see if anything has changed. If it does not, the handset’s registration may have been canceled and we may have to re-register it.
Ok. Let's try to register the handset. Press menu and enter #130. If it says that it is already registered, Press menu and then #131 to de-register, then try again to register.
If you'd like to contact customer service regarding cancelling this service, please visit ww2.justanswer.com. You will see options for contacting them via chat, phone, and email. Have a great day!
