On June 24,2021, Carbonite data backup failed without indicating on the desktop app that backup of data had terminated. Three service calls with remote work by Carbonite tech support did not resolve the problem. My account also shows that I have been charged twice for two different levels of services on the same date, one service is for $164.00 for 2 years of Carbonite Safe Prime, and the other was for Carbonite Safe Plus for 1 year for $119.99, both processed on 05/25/2021 with the same card number. This is obviously a mistake, as I am on automatic renewal. I ask for a refund and was refused. My initial subscription was processed on 05/21/2020 for 1 year. Therefore, I only had one month of working service in 2021. It is now August. Tech support advised me to not escalate to tier 2 because they could lose their job. This is concerning.
