Long story short my wife was contacted to do a wedding for a couple out of state. It was a friend of a friend type situation so we told the lady to check out our Facebook page and see what she thought of our photography company and some of the weddings we had done. She said everything looked great and hired us. My wife drives to 2 hours down, takes the photos at the wedding, we edit them and have them to her in about 2 months. Around 600 photos total and 150-200 edited. We do not here back from her for almost 7 months until she tried printing a 30x20 portrait which she said is grainy due to a high ISO. We told her we was working on a resolution and asked her to send us a picture via txt of the photo she was wanting printed and we would try to help. She has refused to send the picture and is now threatening us with a lawsuit if we do refund her full amount. We have messages from her saying and she likes the photos but because the one will not print likes she wants that the whole album is trash. She did sign a contract before hand and we even caught her altering one of the wedding photos with our water mark on it and posting it to Facebook. We have no idea if she will make good on her threats and if she does where do we go from there? This is new territory for us so any help would be amazing!
