You should've bought from someone with less feedback. People think that powersellers are safer people to buy from but the reality is that they aren't as likely to want to please you because they already have a good reputation built up and one or two additional negative feedbacks will not hurt their overall rating. I always try to buy from the smaller sellers with 100% positive feedback because I know they will try their best to please me. Powersellers tend to be non responsive with their email communications as well.
