Paying more due to their fault

I took out the insurance in my name a year ago and only noticed the past few months that it was in actual fact in my wife's name (which is wrong) but have all my contact details and email address. So what is the first thing you do, you phone them......I phoned them and spoke to a operator from which she advised they will rectify the situation and I explicitly asked if it will affect my premium and she said she will find out and phone me back.....almost a month now and no call yet....end of the month came and all of a sudden they deduct R 130 more than previously, so i phoned again, they said the amount increased due to the updated details (meaning ME being the policy holder now), I questioned them about my previous discussions with an operator asking if the change will affect my premium to which they said they will listen to the recording of my previous call and get back to me....once again no call yet (after more than a week) but they issued me the policy schedule to indicate the higher premium!

Phone me, not email me, phone me as this is what has been promised on two occasions! If I do not get feedback, I will cancel my policy and go somewhere else.
