<prompt> Human: My 82 year old grandfather believed one of those pop ups saying his computer was infected and eventually agreed to give his credit card to someone for nearly 1600 for technical support. He told me about it about 2 days later so the first thing I did was help him dispute the charge.The rep at Chase required me to tell them exactly why it was being disputed, saying it was a scam was not good enough. Eventually I settled on Non-Receipt of Services or Merchandise. Now he has received the forms for this dispute and Im not sure how to finalize this. A couple of the questions or information being asked for: Please provide a detailed description of the servicemerchandise you ordered. What was the reason for your cancellationWill simply saying that a false or misleading internet ad tricked my grandfather into believing he needed their services be enough for the dispute? Will I need to provide much more information here? Thanks for any help. Also just an FYI - Im in IT so I have thoroughly removed all the junk they installed on his computer.  <response>: Falling for a scam is not a valid reason for chargeback...
