I am getting the run around with this credit union...

I am getting the run around with this credit union. I have called 5 times, over the past month, to try to set up an appointment for my almost-90-year-old grandmother. I have been told five different things! I am the one making the appointment because I am the one taking off work to take her. She wants to add me to her account so I can write her checks for her. I was told on the last call that they will have to speak to her to set up the appointment....WHY??? I'm not asking for account information and she doesn't know my schedule. YOU GUYS ARE MAKING IT ALMOST IMPOSSIBLE TO GET A SIMPLE TASK COMPLETED. SHAME ON YOU!!! This is for the Chattahoochee branch.
