I sent in a iphone 4 years ago and received payment as promised, so when I got a new phone I sent in another iphone 4 and have never heard back since. Their website just says that they have received my phone but no payments were ever issued. It's been almost two years now. I'm just wondering why send prepaid envelopes to get people's phones if you don't have the cash to pay them for it? This business is predatory and sellers should be cautioned.
