long history with xfinity/comcast since approximately 1990

All my accounts were previously linked until recently. There were 4 addresses :                [Edited: "Personal Information"].              [Edited: "Personal Information"]                                                          [Edited: "Personal Information"] .              [Edited: "Personal Information"]                                                                                                                                                                                        accounts for :    [Edited: "Personal Information"] and [Edited: "Personal Information"]                                                                                                                                            Since we have been established for so many years our current account does not reflect this long tenure with your company.  In addition, can you please check our current account [Edited: "Personal Information"]  since we are having trouble navigating the website, it is not acknowledging us.  I believe we should be eligible for the Xfinity membership. I would appreciate you checking into this matter for me.  Thank you in advance.
