Edgars Black Lists you for not paying R50

I have been a loyal customer with edgars for over 10 years and now they have given me a bad payment ICT. I make payments each month and it's always automated, however last month my payment was short R50+- and they listed me.

They have not sms or notify me of this and now I am trying to purchase a home, and the bank requires a letter of the settlement.

I have phoned edcon and edgars a number of times and they are not willing to assist. I have paid for all the due amounts and more.

I will take this matter to social media and take legal action if Edgars does not send me an updated letter of settlement and update my ICT.
