POOR SERVICE FROM STORE AND CALL CENTRE

CANT GET HELP,I was a Nashua Mobile client for many years and last year my number was ported to Autopage due to the closure of Nashua ,I lost my phone in the beginning of December and ever since have problems getting a new sim card. when I called the call centre the very first time i was ensured that it would be OK to go to any of their outlets to get a new sim card upon my husbands arrival at the store he was told that there was no info of my account on their system (but they debiting my bank account)I than called the call centre again and was told that I should email my husband id and they will update the system than my husband can go and get a new sim card ,I did this my husband went back to the store the information still not updated and than he was ask to bring a bank statement where they can see if they had debited the account as it shows that the account is in arrears , he did that my account was debited twice in one month for the same amount still no sim card
