Victimised by Dotsure

I have received the worst service from dotsure - bordering on bullying and victimisation. First -I submitted the required photos on Friday. On Monday they sent me two e-mails and an sms asking me for the same documents -accompanied by threats of course. Next I was told they never received my car inspection certificate - this - more than six months after I joined the insurance. I was also told by their employees that she can't get hold of SAPS after I gave them an AR number via the numbers they got on Google - so I must call them myself. I just submitted the required last document and am afraid I might get an e-mail requesting them on Monday and a threat - and yes I include the required claim number in the subject mail. This seems to be a way to delay the process - I am recovering from an accident. They have a hidden no third party involved clause in their policy -strange policy if you ask me.
