Lost quotation

I called Discovery Insure on 4 November 2015 requesting a quote. It was provided and when I followed up on 6 November 2015 to commence cover it was indicated that the quote could not be picked up on the system. The consultant who assisted promised to follow up and get back to me. On Monday the 9th I called Discovery again in the morning and the quote that was referred to was no in agreement with what they had sent me on the 4th. The consultant Mpho Motwa promised to get back to me with feedback. I called again at around 5:30 and I was told that she had already left for home. She hadn't provided me with feedback as promised. I have been chasing Discovery since 6 November with no luck. I have been a premium paying loyal customer since 2013 and sadly today marks the end of my journey with them. I am so disappointed. Its as if they couldnt care less and no longer care about me as their client even though I want to add to my existing policy which will mean additional premium income for them.
