why will nobody help me at cricket

I need three phones unlocked because I HAD to switch carriers because they would not fix the tower by my house it has been 4 and half MONTHS. Would never refund any money or credit the accounts which is two accounts. 800.00 dollars later I finally got fed up and switched now they won’t unlock 3 of the phones I paid full price for I need someone to call me back or something I stayed on hold for 1 hour tonight and nobody would pick up the phone and tried the chat feature 20 minutes before close and nobody would respond
