Made reservations in March, need to change information on passenger for June Flight. Impossible to talk to a representative "they are assigning some one???!!). Nothings ever happens, no response and no way to solve an interactive problem with their "chat referrals" etc. Have tried Twitter, Delta Web Sit, phone (they have the nerve to say it will be a 2 hour wait). Why bother. A large company that can't solve a simple problem unbelievable. Southwest is always available and has clear instructions and resources. I'm going to the airport and confront their representatives before my trip on June 21. The Internet is full of no response reviews!
