Friendly staff but use the online check in

The comunication has been one sided, yet hundreds of dollars in "phone time" that consists of us leaving a msg that we are charged for but no one calls us back. More than one document was sent to my other syblings but not me. This includes court times. Only went to one court hearing and that was because my brother had called on other business and the court hearing came up. Our sister bled the estate, for the most part dry. We requested bank records ect so that we could sue her for a large portion of estate she blew but were told that would be a "forensics accountant" and he said that would be "to exspencive". It was our damn money, not his. Actually, it is his money because he has made a fortune off of us over the last three years while our sister had continued to stall and spend. Like cash in life insurance policies she was told not to. Re financed the house she used moms money to put down one hundred thousand, She was told not to. Att has done nothing about any of this. No answers to our repeated phone calls with questions why she continues to get away with it.
