Settle, settle, settle, ect

How many times must an account be settled?. I asked for a settlement for the account, it was R884 and some change i made a payment for R885 and thought it is over, then a month goes by and i get treats again of summons,ect and an amount of R249 and some change i asked is this the settlement it was confirmed and i payed R250 and thought it is finished because the account from rcs was R800 , but now again it is sms's with treats, of summons how many times does a person have to settle an account, this has gone far enough and it has now become harasment, to settle an account is to finnish an account not to be continually harrased after the amounts that was given by them have been payed...Summons will be issued on your RCS Account.
