Family Mobile I canceled my phone service in January and I am still getting billed in March. I transferred my Walmart Family Mobile plan to another carrier. I got threated with a collection agency letter even though I paid the last of the $46!! Nationwide

I canceled my Walmart Family mobile plan in January.  It is now March and I have not had the service for over 2 months.  In January when I closed out my account they said that I owe $46. I paid that balance at a Walmart store.  Then in the mail a few months later they keep saying I still owe the $46 that I already paid.  when the customer service department is called all I can get is either a computer or a foreign person that is insufficient in English.  No one will talk to me because I don't remember some four digit pin that I supposedly used to create my account years ago. When I go to a walmart store they play dumb and when you call they won't talk to you!
