Terriable service

On the 19th of February I received my first statement from MFC .<br> i noticed that the amounts had changed according to the original deal that i signed with them .<br> Out of the blue they added and extra amount to my deal .<br> i have called them 3 times over the last 2 and 1/2 weeks to try and resolve the issue and and they have still not got back to me with a reason .<br> this is before they have even taken the first instalment off my account . can just imagine how bad its going to get from here out !!!!
