Well, if you have several accts they will call every number listed on the accts, each six times for each acct and each number and it IS legal. Answer and see what's going on if you want the calls to stop.
That number keeps calling me daily and they are not there when I answer. Today that # has called me 13 times! I do have a one of their cards and I am late, but seriously?
If you haven't had any luck, call your State Attorney General. I had the same problem with a dentist that closed all their offices. My Attn. General got all of my money back for any services that were not done.
They have called here (8) times today and I told them my aunt was in the hospital and I would put a check in the mail on Monday . They called (4) more times back to back. I am sure when they get home someone will be calling them.
