From the start my experience of buying a refurbished Samsung phone from Giffgaff was poor. I was not kept informed when my phone would arrive and it just turned up out of the blue. Right from the start the phone ran hot and battery life got worse each day. Two weeks later during my holiday it became almost unusable, very annoying. I sent it back for replacement and again they didn't say when I could expect the replacement, it just turned up by DPD. It was the wrong colour so I complained and demanded a refund. I did get a refund quickly, Giffgaffs only saving grace. Their customer service is like something from the 1970s, absolutely dire. Save yourself grief and purchase elsewhere!
