They called and asked for my sister-who has never used my phone number as far as I know. It is a cell number through the government. I couldn't understand the man talking that good********* Then a recording came on saying to call this number (866) 804-3398. Definitely a scam and a total waste of my time! Please disconnect this number or do whatever you can to block them permanently. Thanks.*** [BBB Scam Type: Other] [Business: Unknown] [Location: MA, USA - 01550]

She stated she was calling on behalf of document delivery services. We have been retained to schedule and deliver legal documents to you between the hours of 8 AM and 4 PM at either your home and she recited my address and asked me to verify it. I told her no one is coming to my home and I requested the letter be sent certified letter and asked the name of the company that contracted her and she stated she did not have that information. She had me write down a reference number and a phone number to call. She gave me 866-804-3398 and reference your file number ******.
