It's good that the EA representatives are aware of the cable interaction problem with the Bolt.Just drove from LA to PHX and back. Charged at 3 EA chargers along the way. On 1, the card reader wasn't working, so I moved to a different charger, and there were no problems. On the last one, it got stuck at "initializing" and I had to call support. They reset the charger and it released from my car. The rep asked what kind of car I had, and when I told her that I had a Bolt, she said "Oh, with the Bolt, since our chargers are so stiff and heavy, you need to support the cable until it initializes". Anyway, I had no real issues with EA (at the Walmarts in Indio, CA and Buckeye, AZ).
You may have done better pricewise if you had subscribed to Pass+ for $4 for a month. It significantly drops the rate and typically only takes two sessions to recover.
Did you use a credit card each of the three times? Does EA still put a $50 hold on each session? And other than the one time, did the card readers actually work? More reports suggest avoiding them like the plague. So, I'm wondering if they've gotten any more reliable.
