Poor service

I am a client of discovery, I called in last week and as they have automated system you have to wait so long to eventually speak to someone. I did manage to speak to agent and was told someone will get back to me. I am actually looking to take out another product with them and no sales person contacted me. Also because there is no even e-mail address one could sent mail to, I'm irritated that I need to recall again for this whole process and again person might not be able to assist me and will say again someone will call!!!
