Unhappy customer

Once again I am venting out my frustrations with the company, I am really not happy with the service I am getting from the company, Since December I have been calling to cancel my handset insurance since I no longer own the handset, my account on the other hand has not been updated to "current" status, I have just been told that my number is deleted and my phone will be off anytime from now (while I am paying every month) and lastly I paid my bill for based on what see online as the statements are emailed late and as a result I am told my account is not up to date, what kind of nonsense is this?
