Waiting for quote and a reply - 2 weeks later

We have been existing clients for many years with Discovery. I called on Friday, 27 March 2015, to request a quote on a HOC policy for our new house. I managed to get a costing over the phone, which I would have accepted, had I been able to get a written quote out of Discovery Insure. The person I spoke to on 27/3 said their systems were down so he couldn't email, but promised to send the quote from his personal email. Nothing received to date. I then got a message from the bond company that the HOC was holding up the entire process and I phoned just after 08:00 on Monday morning, 30 March, to ask for the quote to be emailed to me. The person I spoke to said she had to send it to the underwriters, but that I should have an email between 20 and 30 minutes. I phoned at least four times again on Monday, 30 March. Since then, no quote, no answer to my emails. We have been Discovery Health clients since 1999 on diamond Vitality, have two cars, HOC and home contents with Discovery Insure and have a Discovery credit card through which all our expenses go. This is not the way to treat an existing client.
