Today I tried to fast charge at Electrify America and the plug got stuck in my charge port. My car was unlocked and nothing customer service suggested worked. Other people charging came over to help and also could not release. The only possible solution was to send a tech rep who was hours away. Since I was at a shopping center, I locked and left my car and went to dinner. Returning over one hour later, I tried again and the plug released quickly. Any thoughts on why that happened?
