Was a great place to work up until I got my first complaint in over 2 1/2 years of employment. I worked every holiday the entire time I worked for this company. Also had numerous positive surveys emailed in from the end-users I assisted. From the time the pandemic started even the times before COVID-19 I had worked several pay periods of over 110 hours sometimes 120 130 145+ but when I received my very first complaint they fired me. No questions for me nothing, they didn't even play the recorded call for me like it states they do. Wasn't allowed to defend and or even speak for myself. Was told if I had a rebuttal to email HR. I wonder if that is the real reason I even got fired for.
