They call every day twice at the same time.... when I tried to call back from a land phone. It doesn't ring. Give occupied tone.

And when I called from my cell phone I could not understand the company name.

Returned call and its busy.

I received a call from this number and they told me that I.must pay an amount by debit o credit card immediately to cover a past due amount of.my att account. They don't give me choices when I told them that I will.pay personally in the store
