Unacceptable service

A week ago if not longer i decided to go do a phone upgrade at Vodacom ,went into the store and did the upgrade.I left with the phone on a Saturday and got home with it,Sunday morning i put the sim card in the phone and it didn't work at all.Monday morning i went into a Vodacom store and explained what i was experiencing,i was advised that the phone and sim didn't work and that took me by surprise as the phone was new.I was told to pay for a new sim card where as i had just paid for one on the Saturday and so i did to ensure that i can at-least receive calls,surprisingly enough that sim card didn't work either and the guy had told me that i could go back to the store where i got the first sim card and they would reimburse me for that sim card as it was faulty.Went back to a Vodacom store and i was given a new sim card,they then advised me that the phones sim tray was damaged and i would have to pay for the damages which is surprising because the moment it didn't work i went into a store and let them know so why should i be paying for a phone that doesn't work which i only had for a day. I've never missed my payments and they gladly take the money when i make payments but cant ensure that my phone is fixed and given back to me nut instead want me to pay for it.Is this customer service?

Id never advise anyone to go take anything out at Vodacom as they want to rip us off and have thee most appalling customer service ever.
