poor service ever

I am not happy with the service I got from your assistants which i couldn't get their names because they mumble them i paid off my account i want a confirmation letter i am not told one thing and for the fact that i can't talk to the manager when a customer is not satisfied with the service they tell you leave your details they will call you back is so unprofessional what kind of organizations does that, i need that confirmation letter ASAP because i am being taken from you to Edgars and from them to you. I don't have 21 days i also don't have 7 to 14 working days because your consultant just talk and do nothing about it.
