Worst experience EVER BY WFS!!!!!!

So I have spoken to Woolworths Collections department now numerous times, I have explained to them that at the end of August 2023 we were let go at our jobs without compensation. I then spoke to a call centre agent and asked if we can set up a 3 month payment arrangement, she then said to me to pay my account and then the payment arrangement is in place. I then get called 10 times per day by different call centre agents and to explain the same thing over and over, I then spoke to the last call centre agent and then explained to her what the situation was AGAIN and she ASSURED me that the payment arrangement will be added and updated on the system. I then got a call the next morning again from the call centre to and then I had enough so I BLOCKED their calls. I still pay my account!!!!! And then today 17/11/2023 I get a message to state that I am handed over. I PAY MY ACCOUNT AND YES I do understand that it is in arrears, I do not use the account yet the amounts that I pay then just gets eaten up by interest. So do what EVER you now want!!! I WILL NOT PAY A CENT FURTHER till this issue is RESOLVED
