Pathetic service

I have been going back and forward with RCS for the past 3 years regarding a payment. I have requested for documents which the refused to send. I have now cleared my balance and i have now been waiting for the past 3 months to recieve my paid up letter and everytime i call it takes 15min plus to get through to a consultant and once i get through to someone and explain my story they say its the wrong department and transfer me to another department and then the line drops . This has happened on more that 10 occassions and spend over R400 on airtym over the past 3 months trying to sort this out . I have requested a complaint to be logged on numerous time and even on email and they still did not log it. I am now not able to apply for anything and my lease has ended at my currently place i rent by on the 1st December this meaning i need to live by a friend and my partner and our child has to live by her grandmother . I cannot apply to buy a car cause everytime i do they deckine my application because my name is on ITC.

This is causing so much problems in my life right now.

Can anyone help me with how to get in touch with the financial ombudsman .
