I spent something like 30 minutes once trying to get the ChargePoint app to play nice with my phone (didn't want to install on my Motorola phone) then once I finally got it loaded it took another 15 minutes to get my card added and turn on the charger. Then it finally told me the charger wasn't working after it tried to activate the charge cycle.

I eventually gave up and found a hotel 10 minutes away that happened to have a free charge stall. Took the front desk a box of fresh donuts and asked them if I could spend 30 minutes in their lobby so I could get enough charge to make it home in my Nissan Leaf. Luckily they were nice enough to let me use it and I eventually made it home.
