Cash Generaters review: Phone on buyback

They sold my phone within 2 days of date of buyback although called and was willing to pay for the extension due to severe circumstances, I suffer severe mental health issues and they advised of this also, that I suffer ocd and obsess about numbers so they were also to call when due, also put agreement through on very old acct 10 years ago old address and never put contact details etc, also agreement not signed, I believe they changed agreement also, but both parties never signed, I also never even took full amount of loan I could get, completely scammed please help
