Update -
I think they have some serious reconciliations they need to do to get their accounts all back into good order.
In my case, my On The Go plan had ended in Jan. So when the billing stopped with December, I figured all was good and I was on the Flex Plan as my card still works.
However, they still had me in the system as On The Go as they automatically renewed me for another year. However, I'm guessing that an auto-renewal doesn't automatically renew the credit card charging because I haven't been charged since December. In my case, they were showing a zero balance due. I only recall using the card about 2 times thus far this year, so a retro cancel isn't asking a lot.
Fortunately, customer service was able to correct it over the phone and indicate that since it wasn't supposed to renew, they could switch me to the Flex plan without the cancellation penalty. And she was really nice the whole time. I'm really relieved I didn't have to deal with any run-around and argue over an amount due that shouldn't be there.
So I'm happy and look forward to continuing to work with them.
Since my commute to work changed to 65 miles one way and I don't have good charging options there, it is now my wife's car. And for her local trips, it now rarely needs charging when away from our solar-powered home. So I no longer have the need for the monthly plan. But for peace of mind and to help her with range anxiety, I want to keep an active card on each network. Currently, I have Evgo, Blink and ChargePoint, with Evgo have by far the most convenient coverage in my area.
