MBD overcharge interested and collection commision

I have a problem with MBD Attorneys, I was handed over in 2004. been paying them for the last 11 years every month. The other day I asked for a Statement when I received the statement the monies owing is more then what it was when i was handed over in 2004. When I spoke to Ellen Mokoena and Kerry Olivier apparently all interest was charged and will now be paying off my account, BUT every month they still charge me a collection commission. This is a big problem. I will be 50 and still pay them. maybe I should just stop paying. Please advise how can I foresee my account going down? AS from this point my account is not going down. <br> <br> I have received another call from another collection agency asking when am I going to start paying my account as I have not paid since Jan 2015? I haven't been paying them ever as I am paying you? Please advise why I have 2 attorneys dealing with this account?I have been trying to get hold of someone to explain but with no luck as the phone just rings and when you email them no one gets back to you. <br> <br> I feel this is unacceptable and would like someone to get back to me with regards to this charged and the other collection attorney phoning me for payment?
