lack of communication and no customer service!

My husband received a call to start a policy with the unlimited in good faith. He then gave them my (his wife) tel # as he does not know all the details they wanted to confirm. I then confirmed every detail on the phone with them and approved everything. I was told within 4 weeks we will receive a package with everything in the post and up to date, we havent received anything. When i called the call centre to request where this is, they could not assist me as the policy is in my husbands name, even though any details they need to confirm i can do as i confirmed everything! after explaining my husband works in the field (on the road) on ladders, in roofs, etc and he cannot call and speak to them that is why i was calling, they were unwilling to help. When i spoke to a manager Lerato she accused me of saying that i said they never spoke to him - which i did not say! they then promised to call him but up to date no call! then today i get a phone call to increase the policy rate and policy??? i mean seriously! even after they cant even call a client back! we want to cancel this policy as there is no customer service whatsoever!!!! once again they simply promised to call back???
