False advertising and wasting of time

Yesterday 13 August I did a car insurance quotation with outsurance, I filled out my details on the web and realized that I had done this last year so I cancelled, they still called and I advised that I already did it last year, the lady informed me that a lot could've changed and I told her I was not willing to go through that at this time , she insisted and told me I will be getting R500 of they beat my current insurance, she also advised that it's a no obligation quote. After about 45 minutes they couldn't beat my insurance and she advised that she was going to send a link where I could upload my current policy, o followed up later in the day and I was informed that I do not qualify for the R500 because I got it last year, but the issue is that's not what the lady said when she insisted that we do the quote, I'd this not false advertising? They didn't deliver on what they promised.
