If I could give GiffGaff -100 stars I would. I bought my wife a refurbished phone with a 24 months warranty. After a week the screen started locking and wouldn't respond. The phone was sent back and replaced. The second phone started to have the same issue so was sent back again. The third phone came in a different colour but hey it worked so that was a positive. This third phone lasted about a month then had the same screen lock issue so sent back. This was at the start of February we are now in April and after lots of messages to GiffGaff they have finally got back to us to tell us the camera is broken (WTF it wasn't broken when it went back) and this isn't covered under warranty. We had used GiffGaff for years but would never use them again. Customer service is none existant, the whole company is a scam. DO NOT USE AT ANY COST!!!,
