Poor client/customer service

I am a client for the last six or seven years with dotsure. I have requested a quotation for a third vehicle on my insurance policy/schedule. It has now been six days and all I get is NOTHING. Not sure this is the way to treat your existing clients/customers. I have been called several times by some of their agents. Everytime to go through the whole "rigmorole" and verifying details and such. But no quotation received via email. How do a business work and survive like this. I fell like changing my insurance at this stage. Poor client service for a simple request. Look if you don't want or need my business, then just say so!!
