Joining policy worst experience

Worst customer service ever.. I've met consultants David at Boxer store at Johannesburg. He convince me to join a policy and I join because of good benefits.. I asked him to send concrete proof on my email about the policy.. its been a week since I've been waiting for him to get respond from the office as he says. I am very upset cos I've even pay certain amount that day for that policy but m not even sure that my extended family have been added or not cos his office is very slowly. And also my details were spelled incorrectly and he promised to fix it
