Nspire called us a couple times and wanted a donation. They were to come 7/28/2016 for pick up, marked the boxes after collecting good stuff for hours. It is almost 9pm and no one came and no one answers the phone. I'll be delivering to Catholic Charities I guess tomorrow but don't understand why they call constantly and don't pick up. Just found out it is not a NC but a Georgia place too which they never advised. Don't really care about that but they are beginning to seem not totally legit. Also on phone call, guess they don't give receipts for their pick ups either, hmmmm. They also call themselves HOPE for Domestic Violence? Will ask them next time to take me off their list.
