Fin choice poor service and rude staff.

I have a flexi 6 months loan, I missed one payment due to not receiving my salary, on fin choice app, you are able to get one month's payment skip, at the end of August my account is due to be closed, as 6 months is up, I have requested a settlement letter that I have received via email to confirm a date of final payment is due and set, Yet Finchoice say my account is in arrears for the full amount.when I try to explain to their call agents they are rude and so abrupt. I can't wait for end of August to pay in full and close my account. DONT USE THEIR SERVICE RATHER GO ELSE WHERE. ITS POINT LESS TO MAKE ARRANGEMENTS IF THEY DONT LISTEN.
