Suddenlink deceptive billing Dallas Nationwide

I cancelled due to deceptive billing. I signed up October 17, 2016. By December the $155 per month went to $224. By January they said I owed 446.93 for December 14 to February 14th and I paid. I received another bill February for over 400.00 .  I called February 10th to cancel. I was told this morning that I didn't cancel until February 16th, and I owed February 14th to March 14th. I took the equipment back long before that, yet I am told that I owe for these services regardless. Nothing is prorated because they say the service is on for the entire month. This service is paid in advance and shut down or started remotely. They are like buzzards. I canceled service on Feb 10. They agree that I was paid up till Feb. 14, yet the cancellation was Feb 16. So I have to pay the entire amount for  Feb 14 to March 14.  I said no, and they turned it over to a collection agency. They are not even accredited by the Better Business Bureau. After many hours on hold and being transferred from department to department, numerous texts, and a lot of distress, they will not agree to anything except full payment. I earn more each day than this company is trying to bully and extort from me. They are Ruthless. Horrible company. Shame on these people. My wife passed away last year and I am retired. My new mission in life is to warn everybody I know or meet about SUDDENLINK.  I am waiting for this to be reported to one of the 3 credit bureaus before small claims court.
