Refusing clients to settle

I would like to share my frustrations and the harrassment I am getting from this company. I requested for a settlement discount to settle my Unifi account but they are refusing to give me a settlement. Instead they keep on increasing the amount which is against the law. When I ask for the statement their agents become very rude and speak to me like they are doing me a favour. This company must close down. They are de*****ing PPL. According to the records my account is closed and written off by Unifi.. But this attorneys are trying to **** and loot money from me. Everytime you call them, they give you a different amount and tell you that they are charging R100 on each call you make with them. How do you charge PPL when they are using their own airtime to call you. This company is a ****. I am really frustrated and escalated this issue to the Ombudsman and NCR. This company must be closed. Today I am struggling to buy a house because of them. I am tired of this ****mers. They are reaping off money from poor South Africans.
