Unacceptable policy change

Seriously, it's my first day as a Budget client and we are already off to a bad start.. I got a quote this morning for my car insurance and the consultant says that they have the quote on 'market value' so they will leave it at that.. So I said no, I want this changed to the 'retail value' so that change was made on the quote.. So I receive my quote and the premium is R680.38 and it states retail value.. So I requested a call back later to decide if I would like to proceed.. So when they called back later, I decided to proceed with their quote.. There was one change on the quote, their system picked up that I was married so I requested to have that changed to single.. My premium went up by R8.00, which is understandable.. So I proceeded with the insurance and canceled my existing insurance.. So when I received my policy schedule, I noticed that I was insured for the 'market value'.. I called Budget immediately to have this corrected as I was not informed that it was changed to the 'market value'.. Now they want to increase my premium to over R700.00. That is unacceptable.. I requested that they listen to both phone calls, the initial quote and the underwriting call.. I specifically stated I want my vehicle insured for retail value and not once was I informed that this would be changed to market value.. and now I have to wait 7 working days for a response? Is this really the service I can expect throughout my journey with budget?
