After sfe have approved my application for the 24/25 application and asked me to upload my parents is income to get further support I did and seen my first payment that was scheduled on the 23 of this month they sent me a email about an interview , during the interview I found out that someone has applied for pip on my behalf and has even sent them a letter in my name I have explained to them that I have not applied anything like that and they told me they will investigate and get back to me later they sent me a email saying they believe it was me who uploaded those evidence therefore they have blocked my account for 6 years. I have asked to see the evidence that was uploaded and until now I haven’t received it I have also asked them to review the call that the person made pretending to be me and to check the phone number they received the call from and compare the voices they have recorded and until now they haven’t . They now sent me a email saying they have closed my case and if I don’t agree with their decision to make an appeal , I did and waiting for their response. Any advice ?
