Incompetence from agent that costs me as a client

Hi Last year Dec I was in a car accident and called budget for assistance, 1st call was for tow truck since my car was not working and driver mentioned not much of damage seems like the RADIATOR needs replacement, so I took what heis as I know nothing about cars and had never put in a claim. So when I called saying I want to claim and mentioned my radiator was damaged the lady said unfortunately radiator isn't part of my cover I will have to contact their warranty department, so I told her OK transfer my call cause I need my car fixed. So I spoke to another lady in that department only to find that she is actually selling me the warranty insurance and told her OK find I can take so long as it starts now and get my car fixed, but only to find there is a waiting period which I couldn't wait for since I use my car to travel to and from work daily. So I had to find other means as my insurer has met me down, mind you I have always paid in time and never lodged a claim from time I joined. Now the only place I thought of was where I bought the car cause I know no other people who can assist. So when I got the I explained that I been advised car radiator needs to be replaced since I was in a accident and they said they cannot just take my word for it they need to strip and access incase other parts are broken. The T&Cs of that where should I refuse the quote then I am responsible for the strip and access fee R4k+ Unfortunately woute was to much and had to pay, was adviced by a colleague to call insurance again but don't disclose much just say I want to claim I was in a accident. Gladly called and claim was put through and car was fixed well including the RADIATOR which was denied in the 1st claim call I did. Therefore the reason I'm writing to hello Peter now is I have done numerous calls explaining my story of how *********** the lady was and she cist me R4k+ unnecessary and I want to be paid cause if she had done her job and didn't deny my claim or try to boost warranty department sales I wouldn't have went to my dealer and paid R4k+ for sweet nothing. Apparently she didn't even log onto my profile because they can't seem to find who it was since she just transfered without logging into my profile and see what in covered for. I'm frustrated each time I call I have to explain the same story get pity and be told they will escalate, it been weeks now no feedback at all. Next email will be to social media and more with this.
