I had ordered a phone via eBay. Came with a warranty. It was bad. It was sent back with an RMA. I got another phone. It was worse. I sent it back with an RMA. I wanted a refund. They said they would refund. They didn't. They sent out another phone today. All of this is on record with Paypal. I would like to rescind my comment I left for them on eBay. How do I go about adding additional or changing comments?
