IPhone

I bought an IPhone with blue label connect campany they delivered the phone that was not working at all unfortunately I did not noticed, I swap my card and take a phone home with a hope that maybe the problem is with the betry maybe it flat when, I went home I charge the phone still it wasn't working I call the driver immediately the driver said I must call the campany I did on the same day they did not came to collect the phone they came few days later to collect the phone after a month they call me and told me to pay R700 I ask them for what they said they Iam the one who broke the phone they did not tell me how and they are still deducting my money and can't reverse the money because I swapped the card
