FNB Smart device

I had a smart device account in 2014 which defaulted and was handed over to legal. I made monthly payments then in December 2018 paid off the account with a final payment of R5000. ever since then I have been trying to get a clearance letter. I have contacted the smart device customer care who then put me through to collections yet no one is ale to assist me. I have sat for hours not on ly on the phone but in the secure chat feauture built into the app. I have also emailed and Patience/ Precious Selokela has promised to get back to me or escalate my query and nothing has happened in 4 monts since I first emailed her all my supporting documents and information. I have been in branch ony to be referred to a hotline that is quite frankly USELESS as no one wants to do thier job or a little bit of invetsigating to see how best to resolve my query!!!!!!!!!!! This is frustrating as I need the judgement on my name cleared yet no ne is willing to assist me and I keep getting sent form pillar to post.
