I'm reviewing my bill because of high charges starting in Jan 2018. And it looks like I've been overcharged by $80.00 on the past due amount listed on the Mar bill due April 27th. Can someone take a look at my Jan, Feb, Mar invoices and the associated payments made between Jan 2018 to April 11th, 2018? It doesn't seem to add up. Thanks! for your attention to this. I am also looking beyond those dates as well.
