The Chains of Accounts.

I've been an account holder with edgars for more than twenty years now, had different products with them including insurances. I lost my permanent employment in 2017 and I by almeans kept my account in good standing, but now of late I've been struggling to make ends meet. The last time I communicated with them my debt was around R7000+, I made arrangements to pay and only managed to pay varients of R500 and sometimes R600 of which is half the required instaments. Now things are bad and I requested them to Close my account and that I make other plans / arrangements to settle that... My request seems to be falling on deaf ears!!! Now my fear /is. This amount is growing bigger by day due to the interests added and of late they sent me a message that I have been handed to debt collectors... Pls Help. Will this debt /account be canceled /sc****d by my death.
