Avianca Airlines

Why don't they answer the phone? They fixed an error on my ticket,on time. But they never answer the phone? Why?

The women that work at this office are rude and have no training in customer service. I have been there once and the experience was horrible. They treat the customer badly. On the phone today asking the woman that answered the phone for directions I had the same experience. The woman hang up the phone when I told her to please listen to my question. I needed the correct address to enter it in Uber to call the ride for my mom from the doctor's office to Avianca. I will never fly Avianca unless they change and train their employees, they are horrible. I believe the woman's name is Consuelo because when I call back the same number she now does NOT answer and the greeting says that her name is Consuelo.
