Incompetency and bad service. Places risk on customers.

I have taken up insurance on my new vehicle on Monday, 26/02/2018. The *********** call center agent that assisted me added the incorrect vehicle description on my insurance. I was contacted an hour or so regarding this, and they have stated there was a mistake, and when they have changed it, the premium would not be R705.10, but will increase to over R1000. That was ridiculous, and I hung up the call. I then proceeded to ask my agent at Volkswagen to phone, because I was too upset. He said he would sort this out. Someone on the phone stated it was a system error, and the installment shouldn't have changed. He stated that the lady I spoke to should not have given me amounts and should have seen that there was a system error. They said its sorted out. I as of today did not receive any documents with the updated vehicle description. I am so stressed now as I'm scared to drive my car, because I don't think I'm insured properly now! All I can assure you is that there is a huge mistake with such big installments, as my brother took out the same policy with Discovery on his car (exactly same make, year and model), and his insallment is the same as my first R705. I will not pay anything more. I was also encouraged to go to Ombud and seek legal action. I will most definitely do that, as call recordings and all were done by law. So what will you do about this situation, because you made my buying a new car a terrible experience!
