So on June 27th, we needed a taxi to the airport for 6 people with luggage going to CDG. On this forum, I was advised by several folks to take G7 as they were the largest taxi company in the city and I read lots of great reviews. So I called them the day before and paid €5 extra via credit card to book a taxi for the next morning at 8:15am.
At 8:15am, I get a phone call from G7 stating that they don't have a taxi for me even though I booked the night before and I would have to wait or I can cancel. Not having another option I said I would wait. At 8:30am they called me back to say that they still did not have a taxi to take us that could accommodate 6 people. I told them that we had to leave so forget a single taxi if they can't find one and send 2 regular taxis. They said they would call me right back.
I started to get concerned and immediately googled the Metro to get to CDG. This was not an initial option for us because of all the luggage and because my mom has bad knees and has trouble with all the stairs. To make matters worse, it was raining that morning. At 8:45am, I get another call and they said they still can't find any cabs and asked me what I wanted to do. I told them they are leaving me without any options and i have to leave immediately and will have to catch the train. They told me that I would not get my €5 refund because I was canceling the reservation. I yelled back at the guy on the phone and said i wasn't canceling - they were a half hour late and couldn't tell me if/when they could be there and were leaving me stranded. He screamed back at me and told me too bad. I hung up on the guy and started hustling my family in the rain to the metro. This was morning rush hour on the trains, and lots of stairs with lots of luggage and a mom with bad knees. Not fun, but we made it just in time to board the plane. Fortunately, our apartment was close to Les Halles where the RER B train took us directly there.
In any event, I will not be using G7 in the future and would advise anyone to have a back up plan just in case your ride doesn't show.
