Client service

I have experienced the worse client service from this company. They should not be in client service if they cannot assist their clients. I need to get some urgent information but am unable to do so as they cannot take your calls and never phones back. I keep on leaving messages for Natlie as she is never available to talk to, but she never returns my call. I asked to speak to her manager but the person is on leave, therefore also not available. I then requested to speak to her manager but he is always in meetings and cannot speak to me. I was informed that the only way to communicate with him is to send an email yet the email address given is not correct. There is just no way to speak to these people, although we are paying them a fee for the admin work they do for the Estate.
