that attitude seed bank seem very arsy. you could always try and say that as a souvenir the seeds should look remotely like a cannabis seed and what you got sent does not look in anyway way or form like what i ordered, natural or not if you ordered a seed u want it to look like a seed.
other than that mate id say ur screwed
try Rhino Seeds (Cannabis Seeds) never had a problem and they will always replace a bad bean.
or Nirvana seeds
