Bad service

Im not sure what to do anymore or even where to start, 1, my contract was cancelled due to this company service, bad service, incorrect bill every month, cutting of line even thou bill its paid, and when you call the staff doesn't know. 2. I have reached a point where i decided i will move to another network and since i know my contract was due in December i gave cellc 30 days or what ever that is required for them to change my number to prepaid? After all the stress you have been in our lives we want to move from you but still we cannot as you keep on doing what you want. I need this sorted as im ready to go to the ombudman or Icasa if i have to To my surprise i realized that im not getting calls for the past 2 weeks. when ever we try to call the call center number cuts off. tried to use my phone and call someone and a different number pops out. I will like to know who gave permission to change my number as i made it very clear that i will keep this number.
