Finchoice Account

I had an account with Finchoice about 4 years ago which i paid off. Yesterday i received an SMS from SSDA saying i need to pay R249.95 urgently, so i gave them a call to find out what that was about and i spoke to some lady who said i need to pay R749.00 that i owe to Finchoice. i asked her to send me a statement as i do not know anything about any monies i owe as that account was closed and she said she will send the statement, i am still waiting for the statement. Today i receive another SMS that says i must pay R195.93 tomorrow. number 1, it has taken these guys four years to realise that i owe finchoice?? number 2, they gave me 3 different amounts that i apparently owe in less than 24 hours. what **** are these guys running??. I am not going to pay that money as the money i oewd to Finchoice was paid a long time ago.
