MTNHVRCrepair centre

I send my blackberry leap phone in for a warranty check,because we could not hear the phone ring it was only 3 week old. we give it in at the brakpan branch. after 10 days they told us they have send a refurbished phone to replace my phone. We denied that phone and told them that is a brand new phone and we want it replaced.<br> the dealer send the phone back to the repair center and they send us the original phone back. when I phoned the to find out why didn't they replace the phone with a new phone they rep**** that there is a dent in the phone and the paper work was not filled in correctly. we a I spoke to the store dealer they said everything was filled in correctly and the phone was in perfect condition.... according to the dealer they say that the repair center do not want do replacements and give any excuse not the give out new phones......I cant accept this we had a contract with a new phone and I want a bran new phone because that is what I AM PAYING FOR ' A NEW PHONE' they keep passing the bucket not to replace the phone
