Wrong amount of Money debited and wrong policy

I joined King Price with such great service from one for the agents. I was so please with the price their quoted for my house and car(R681.44), that i cancelled my current insurance.I took the offer and gave my old insurer notice for 1 month. My policy was e-mailed everything was set. In August however to my surprise I was debited 795.45 and when i called in to find out why, i said oh no its because my access was so long and i said on the agreed policy they sent me that was the agreement, than they said no maybe its because i didn't install a tracker, i installed a Bmeax into my car which again i assured them that it was what we agreed on before. Than they said they would get back to me. when after a few days no one got back to me i called again was put through to retention's, assigned to Clayborn, there he said he would have to listen to the calls and get back to me. A week later i didn't receive any feed back,i called again and he said he assumed someone had called. He said he would get to the bottom of it before the next debit date. This month another debit order with the wrong amount again. currently i am car less and still have not heard a word from them.
