Neglected to pay Creditors

This is really so unfair to be treated like this we have paid all our outstanding accounts and Debt Busters told us that we will have our clearance certificate by the end of October 2021. now they say that there is still outstanding fees at FNB. we contacted FNB and Debt Busters neglected to pay one of the accounts - FNB sent a letter to Debt Busters on the 8th of February 2017 stating that the account has not been paid by Debt Busters and they did NOTHING about this - they have deducted our money every month - i followed up on the accounts on numerous times and they guaranteed me and sent me statements that accounts was paid. where is our money gone to then and why did they not sort their problem out? NOW just when we thought this nightmare was over they come with stories and we cannot get our clearance certificate. this is so unfair treatment. there was so much money paid every month and they do this to us now - now when we thought we can start breathing again we find out that they have neglected payment to accounts. i have sent the mail from FNB to DEBT BUSTERS twice and so many follow up mails after that and they keep sending me emails saying that i must get a paid up letter from FNB WHICH I WILL NEVER GET BECAUSE DEBT BUSTERS DID NOT PAY THEM. so what must i do now? when you try to contact them you NEVER get through their lines are always busy - when you email them they do not answer with any feedback they just say that now i must sort it out. how unfair is that? we have trusted them with our money and trusted that they will sort out and pay the accounts every month, it is almost December and we can still not get our clearance certificate or begin the process to clear my husbands name. we are really hurt and very sad about this
