Good afternoon. If you unsuccessfully booked a car using Lyft, then after you send a message in the app, replies from Lyft will go to the messaging function, which looks like a chain of text messages. Honestly, getting a full refund from Lyft is unusual, unless something particularly bad happens during your trip. Instead, lyft customer service may offer you a discount or credit for your next trip if your driver takes an ineffective route or if you don't get the discount you were hoping for. You will only receive a full refund if something went wrong with your ride, such as a serious collision with your driver or an accident.
