RCS/EDGARS AND USURY! *******?

I thought I had paid up my Gears account in 2019 or 2020. However I apparently left a balance of R6.00 yes SIX RAND owing, of which I was not aware. Apparently, I was notified to a defunct email address, that any account owi go more than R1 YES ONE RAND, will be charged R28 per month until it is paid. They have been charging me R28 per month since the 1st of September 2024 because I owe them R6! They refuse to close the account until I pay this usurious amount and will keep charging me additional amounts of R28 per month until I settle. For R6 on an account which I have not used since 2019!
