Discovery Invest Annual Income Review

My Discovery Invest Living Annuity has an annual income review date of 09 June. Normally I receive an annual review letter from Discovery Invest 3 months ahead of the anniversary date so that I can review my annual income. Today is 11 March 2022 and the next anniversary date is 09 June 2022. I have not received any correspondence from Discovery Invest yet. I sent numerous emails to query the matter with no response. It is utmost important to me to do the annual review before the next anniversary date. I am now very concerned about their administration that is not up to date.
