Worst service ever

I work with a broker called J van Freden Financial Services and my insurance is currently with Bidvest insurance. I had never in my life experienced such bad service from any insurance company. I phoned in to move a debit order date. I was told that it was done and my next debit will be from the date that I changed it to. Guess what the day come and the premium didn't go off. It cost me another call to try and sort this out. I sent many emails aswell.There was a mail sent to he "big boss" but this guy just didnt give a ****. A month later on this day they took a f....cking double debit after I tried my best to sort this out so it won't happen. It happened previously that they took a double debit and nobody ever tried to sort it out. I will leave a complaint with the ombudsman. Will also tell everyone to be aware of this compan. Shocking experience
