Rude staff, lack of training!

The staff at Edgar's needs training on how to speak to customers, the are ridiculously rude. I went with my mom at the Edgar's in Westgate, we wanted to find out why my late father's account wasn't decreasing despite the fact that we've been paying his account religiously every month. Instead we got a teller named Kris who screamed at us in front of everyone, instead of giving us the relevant information that we needed, he used rude terms when he addressed me to his co-workers. Eventually after the dispute we got the help we needed but what I don't understand is why it had to get ugly before we got help. Their customer is just beyond terrible, no customer should ever get into a confrontation with an employee before the get help!
