faulty phone/bad service

I bought a cellphone via intellicell and the phone is faulty I was advised to send to Vodacom shop. the consultant refused to take the phone advising that intellicell is the one who suppose to collect the phone. Vodacom Newmarket repair refused to contact intellicell. they said I should be the one contacting them. a blame game is between Vodacom and intellicell and I should be the one who suffer in the process.
