My sister committed suicide 2 years ago. At that time, AT&T sent a number of overpayment checks to her; but since there was no probate of her estate, they were never cashed. She left a virtually bankrupt estate and her husband at the time committed suicide 10 weeks after her death. I contacted AT&T about her death and they said that all of her accounts were settled. Over the last few weeks (now 2011) I have received a number of calls and a reference number claiming that she owes money, refusing to provide me with details and demanding a copy of her death certificate. While I have little problem sending copies of her death certificate out, I am bothered by the fact that these accounts were settled. I believe that EOS is trying to collect on something already put to rest.
