Account Handed Over

My name is Pule Letuku id number *** I was employed by Edcon from 2006 till 15th of march 2015 when I was retrenched,I had a staff account and when I was retrenched I was asked by my Human resources that the account will be paid by the account protection plan as I was insured and I signed all the documents stating that the insurance of which is Hollard will pay the account, to my surprise the company ddnt pay the account and they have handed it over to vvm for collections and they have listed me at ITC and I have been quering it with both Edcon and Hollard and everytime I phone they tell me that its a mistake it was suppose to be paid and the matter will be resolved in 48 hours till today nothing has happened and ive been getting the same story everytime, so please Edcon and Hollard please sort out my account as now you have listed me at the credit bereau for your own mistake.
