Rude consultant

I done a application online to open up a savings account for my son I did not know they don't do that for children younger than 18 anyways long story short the consultant who called me was extremely rude when I asked him why they don't open up accounts for children he literally put the phone down in my ear... What kind of person that does to me its like he just wanted to make a quick sale for commission instead of doing his bladdy job he has no manners whatsoever please get professional people to work in this kind of industry who are willing to help and explain to customers because you will end up loosing customers due to lack of respect and manners in your business!!!!! I will definitely be taking my business somewhere else where I'm treated with respect.. I will never invest my money in a company with people who lack respect for customers I'm highly disappointed and disgusted...
