No positive response from Hollard to change detail

I have submitted 4 requests to do changes to my funeral policy at Hollard insurance. The requests for assistance have been on 13 and 21 January, 3 and 7 February. All proof of submissions are on my mail and one reference number ***. No positive response received and nobody coming back regarding the changes I need to do. I want to find out about my son on the policy as a student which turned 21 end of last year, secondly my wife's name needs to be added and someone else removed. There is also the querry I have regading adjusting the cost per month as the amount of people stays the same on the policy. I need Hollard to respond positively and do the changes requested. At this stage I am considering cancelling my funeral policy with Hollard due to this poor service. My ID no *** and the policy number for the funeral policy at Hollard is 526495.<br>
