Worst customer service

Two months back I was offered a settlement discount on my House & home since they have been sending me statement even though it was handled with Consumer Friends, I paid House and Home and they send me a settlement letter, they say I’m still owing money this was two months ago and still the amount still reflect on the statement as outstanding. Please clear this matter should have been resolved and I’m about to finish paying off my account but with issues still pending it’s not helping. Cause even Debt Buster have been trying to get this matter resolved ever since I received feedback but no one is getting back to us or provide feedback. Cause it should be cleared by now. Worst customer service ever
