Old Matual Greenlight are ********

I have a green light funeral cover for myself and my parents, my cover has an annual increase but my mom and dad’s annual premium I opted for no increase. I have had these covers almost 10 years now, last month I received a statement for an annual increase effective December which is my anniversary month but it indicated that my mom’s annual premium will increase by 42% and my dad’s annual premium by 35%. I don’t know what is the reason for this because I specifically requested no increase on their premium and it has been so for almost 10 years. I called Old Matual but I was told the premium on their side shows as the same and when I asked about the statement that was sent the lady placed me on hold for 30 minutes and then dropped my call. I sent an email to Dumisa Mhlamo who is supposed to be my financial advisor almost a week ago but he never bothered to get in touch or even acknowledge my email. I believe this was done on purpose in hopes that I will not check the statement and be surprised when they debit my account.
