Absolute ********** service

I have not had or used my internet since the 22nd of September, after many fights and disputes I put through a cancellation request on the 13th of October 2017. I received the first bill which the credited and only charged me for what I used. I then paid it and unplugged my internet. I have since not used or plugged in my internet router. No one has asked to come and fix the line or even told us that the line has been fixed. We have now been billed again. Please fix this immediately.
