Pay no interest or fees if the loan is paid back to Finchoice within 14 days is a ****

I requested a loan on the 20th December of R25 000 and a reloan on the 27th of December 2018 of R10 000. I received R10 000 on the 28 of December and on the same day i wanted to settle the loan total of R35 000 (R10 000 received this morning and R25 000 received on the 21 December). I requested a settlement quote to settle the amount by 31 December 2018 and the quoted amount is R37 935.23. Finchoice terms and condition state that "You pay no interest or fees if you pay us back within 14 days". I called the call centre i was told that because its a reloan i do not qualify for a 14 day waiver period. Then i asked if they can show me that in the terms and conditions. I spoke to 2 consultants of which they could not prove to me where it stipulated in the finchoice terms and conditions. According to the consultants there is nothing they can do. So they just said sorry you will need to pay the full settlement amount. I then paid the full R37 935.23 today on 28 December 2018. I just want my R2 935.23 back and Finchoice need to revisit their terms and conditions.
