Bad client service, Right to rightfull information

So I see an advert on TV, 'Sms the word *car* to 44144 and if we can't beat your current insurance premium will give you R500, better yet if you ha e not claimed in the past 3 years will give you R100. I sms' s received a call from the agent and at the beggining of the call I specifically informed the agent that this is with regards to the advert, he said oka let's continue. He takes down my details and realized that am an existing outsurance client for a different policy he says to me let me transfer you to to the other department because you are an existing client. He does that and another agent picks up the phone and continues with my qoaute. Right at the end I told her that she may contact me after 2 hours I have a 4 month old baby that's giving problems infornt of me. I also wanted to get my policy schedule for my current insurance to be sure how much am paying since premiums were decreased due to Covid 19 relief. Fast forward later I call back and speak to a different agent explain the purpose of my call and she blatantly said to me NOpe you dnt qualify due to you being existing client for that promotion. It is not my fault that the first agent did not give me the right information at the beginning of the call. I want my money. She reffered the matter to management to sort it out I have not received a call from them. As a consumer I have the right to rightfull information which was not provided to me at the beginning of the call. I request that you listen to the call and sort out this matter as the error lies with your consultant not me. Outsurance do the right thing and pay up the R1500 as per your adverti*****t as my current insurance premium is lower and I have not claimed in the last 4 years
