Bad Service and dishonesty, no reponses,

Bought the phone in September. Phone's microphone broke down in October and sent it in for repairs in November at the Loch logan/ Waterfront store. Phone is still in repairs Feb 2015. Store assistants promised to call me in December, but no call has been made to me. In January i called the store to find out what is happening with the phone. I was told to pay to pay +-R988 for a 2 month old phone to be fixed, which i then refused to pay because the phone is practically new. I was then told to pay R188.10 for the phone to be couriered, which was then paid in on 12Jan and they also asked me to fax the proof of payment which i tried doing, but the fax number did not even exist. on 26Jan i went to another the college square telkom branch and told the agent my story, he unfortunately could not help but advised that i should not have been even asked to pay any fees for a 2 month old phone. i went to the Loch Logan branch on the same day and after we waited for an hour or so, she advised that she would fax the proof of payment and also call to advice about the delivery times of the phone to be couriered, which no call has been received. i again went into the store on 30Jan and no action.
