Bad experience

I Bought a phone at woodmead vodafom last week Wednesday, brand new. The phone was charging but not up to 100%. On Friday I took it back to the shop and the way they treated me it was like i stole the phone. I was told to take the phone to vodaworld and at vodaworld I was told it would take 3- 7 days. Today I went to fetch it and was told it was rebooked. I'm disappointed because I thought I'd get my phones today. I needed them to refund me or give me a new phone. Their service is very poor
