Accounts

If been having account issues for 2 months.... I called the contact center and they told me that my problem has been resolved. Now this month I have the same issue. I went into the store where I was told that they can't help me... After having to put up a fight and having another person come in and having account issues....... they helped me and told me my accounts was up to date....... Now today I'm receiving the same SMS telling me my account is in arrears
