Hi, i submitted work that was done by someone else as in like those website where they can help you with ur assignment, and at the time i really needed help, but i now know how wrong that was, and tht it could affect me badly, also i have already gotten the degree. and now the 'company' who did the work are blackmailing me because i said i did not like the work, and are saying they will contact the university and tutors and send invoices and screenshots of conversation showing i did not do the work unless i paid them to not contact them and delete my details, which i did not pay cause i thought it was a scam. But now im scared that it might actually be true and they might contact them and do you think my university will revoke my degree or take legal action around this or is it probably just a scam, im just very scared, even though this is the consequence of me doing something like this and not my own work.
