Complaint about service

<p>I'm complaining on behalf of my younger sister who purchased cellphone in April 2015 at Exact store with account then on the 21/12/2015 return the phone (Samsung S531019) to the store after she experience a problem where she is busy talking it switched itself off. My younger sister on the 30/12/2015 get a call from repaired unit at MTN informing her that she must paid R 449 for quotation and refused then advised to paid R330 for transport fees if she need the phone to be returned to the store. since that day till to day we are straggling to get that phone.</p>
