You can cancel the phone service but you will have to call into the Customer Loyalty Team at 1-888-438-6673, Monday-Friday, 8 AM-8 PM, Saturday-Sunday, 9 AM-6 PM. We would definitely be able to assist you with this. Please reach us on Twitter at @CoxHelp, visit us on Facebook, or email us at firstname.lastname@example.org.
