Terrible customer service!! I went to return internet device to this location, and there was old lady who looks like 90 years old(white female with dark skin) working there. She was so rude!!! She accused us of not returning a device which we never rented from the company!! Yelling me to bring it back!! We kept explaining that we didn't rent it from beginning, but she didn't listen to us. Other lady came in and looked at their system and figured out that we didn't rent it from beginning. The old lady needs to retire!!!!! She was #@$*#!!!!
