CANCEL MY CONTRACT

I am over my two year cellphone contract since September. I submitted the cancellation forms in September. I was told I will be contacted by the person who is dealing with my cancellation. I have been waiting for this person since September. Everytime i call i get the same answer, we are emailing the person who dealt with your cancellation and they will contact you. I am told they tried to reach me but couldn't so i gave them two numbers for in case and I am still waiting. I am being charged for each month that goes by even though i have ported my number to a new network. What is going on???
