Account handed over for legal action

Hello,<br> <br> We have an account with Russels that we settled on the 11th Nov 2014. We made an<br> installment payment on the 3rd and then settled on the 11th Nov. Somewhere mid 2015 we received the 1st call from Russels saying we owe them R4000. We went to Joshua Dore as they are now amalgamated with Russels to enquire. I went to Beverley we looked on their PTP system and it showed nothing only a balance. They logged a message on system in order for their head office to assist, then nothing happens we receive calls again saying we owe russels money. We then visit the branch in kathu again to enquire after a long struggle and lots of calls they show me on their system that its written off, but today 19.11.2015 we received a call from lawyers in cape town informing us that the account has been handed over. I require your assistance as this shows bad debt on our ITC record and we are also now going to be charged collection fees on that amount which I will not pay. I am not going to pay for someone that did not do their job. I have proof of payment and I will also engage with their customer service as I will insist on every conversation recorded and every sms send to us.
