Query on Edgars account

My name is Patience Sigasa I have been struggling with getting Edgar's to explain or give clarity on my account. Last year in September I stopped paying my funeral policy that is lined to their account. Then in January they sent me an sms saying I owe them 2000 rands. I went to the store and I couldn't get customer care because that's when RCS was busy with taking over the store. I was then given an email address and 0800... number to call. With no luck no one answered and the email was not answered. Yesterday I went back to the store to try find out why I got an sms stating that I owe 6000. On a monthly basis for the policy I only pay 158 rands but from September 2020 to August 2021 I now owe them 6000 rands.
