updating accounts

i had an out standing account with discovery from 2013 when i left the scheme of R525. they contacted me about the amount and i said please send me proof of where this is coming from witch never happened. so now in 2015 i want to app**** to discovery again in witch they say i must pay R525 first and so i pay the R525 and my account is settled so i start 1st of feb. up until today i am still getting sms's to say i must pay R525. go and get my free itc report today and what do i see discovery has listed me as a default. they don't even put by the remarks that it has been paid. PLEASE UPDATE MY ACCOUNT AND REMOVE THE DEFAULT FROM MY NAME AS YOU HAVE GOT YOUR MONEY
