Sanlam annuity

My retirement annuity from Sanlam is about to pay out. A couple of months ago I received a letter from Sanlam stating in brief the options I have because I want to let this annuity to continue. I was referred to a financial adviser from Bluestar financial services or Glacier. I'm not sure what their name is because I found both names in their correspondence. In the same letter I was warned against removing the annuities from Sanlam itself because they got better options. Bluestar only informed me only in part of an option they have for me. I wasn’t impressed with their services because of the lack of feedback for me to make a proper decision. I'm a total novice when comes to investments and need guidance what to do with the investment. When I ask for a basic percentage growth of the options, I have was send a stack of Investment information that I totally do not understand. In the mean time I phoned Sanlam trying to get someone from them to help me because in the first letter the indicated that they have better options. Only lip service and every time I speak to somebody, they told me they are not allowed to give me information of the options they have, and I must speak to my consultant. I received again a letter informing me against removing the annuities from Sanlam itself and that their options are better. The letter was emailed from Kowie Uys to my financial adviser to me. I then phoned Sanlam asking to speak to this person I was told I'm not allowed to. If I had known this was the bad service I would get when I invested with Sanlam forty years ago, I would have stopped it immediately. I'm at a dead-end here where no one in Sanlam is able or willing to give me advice on investing so that I can have a better future.
