I received a letter from forbes douglas on 28 oct. I filled in a form then sent it back to allow them to start chasing them up. I now have received further letters from them with more forms to sign regarding ppi's from a few different companies. I haven't signed these ones. Should i send a letter back saying stop. I have read there terms and conditions and it says if i dont carry through, they can charge me but there wrre no t&,c's with the original letter
