what after service would i have if they cant even come back to me?????

Good morning, I submitted all my info via online to open an account at Edgars, and they have phoned me to send correct info, as there have been a problem with my surname, and its been 2 week without a word from them, if they wont help me at least they can give me valid reason for not wanting to assist me, i have an excellent credit score, .......I tried complaining to company directly at customer care, but only receive emails, that it is a no reply email, and they will get back to me in the next 48hours, well it has been almost 2 weeks, i expected a reply by now????????
