Poor Service DIscovery Life

I have been trying to increase my cover and add benefits to my policy from the 13.03.2018. From dealing with the sales call centre, policy servicing department call centre and email team has been the most exhausting experience ever. I have still not been able to get this resolved. Not a single agent had attempted to make the experience an effortless process. I just keep receiving multiple quotes, requests to send specific pages , and after all of the draw out processes, I get told the quotation has expired. I am not trying to get a new quotation and after 2 calls this morning, I still dont have it. Extremely disappointing service from Discovery.
