Bul**** to pay R55 000 interest

Woolworth credit card handed over my account to VVM attorneys with the incorrect statement of amount. I owed them 26,556,97 and they now demanding R81 000. I have been paying under debt review since 2017 and protected by same. They add interest on the same amount I was paying while under debt review. I have been emailing them sending them statements to prove my case and getting annoying calls from VVM to pay the amount in dispute. I am real sick and tired of their stinking customer service which is useless and not listening to the customers. They just try to bully me demanding the amount which I never even owe them as principal debt before.
