My Uncle is on his 5th year battling cancer lung and brain. He is currently undergoing brain radiation through a helmet of sorts. His memory is slipping badly the Dr gave him pills there not helping. Past few days I have been to his home to clean and do yard work I noticed a Number calling repeatedly from California 30times back to back. I asked if he should take the cal he said no. I not he had prepaid card from Walgreens when he opened door to let me in. Later he asked me or my fiancee to go to Walgreens with id with him I thought he was to weak to get own meds or something. She went I was covered dirt from yardwork. She told me that same Cali # was calling and he had her purchase 1k in prepaid debit cards after he purchased 1k. The past 3 days this # has been calling. He sent 3k alone yesterday. What type of scam is this? What can I do to help my Uncle get away if it is a scam? He would never do this in his right mind!!🤢
