Denial of full service by Axxess

As I shall be leaving overseas in early March, I scheduled that my data contract with Axxess terminate at the end of February 2022 During the 28th, I no longer had data available The Axxess agent told my that "Cancellation are done after midnight on the 28th of February and the today is the 28th" 1. Although Axxess offers 3 months roll-over of data, they refused to allow to use this data 2. Cutting off my service before the month end is not acceptable
