Mobile Phone won't be returned

Following my previous complaint over two weeks ago regarding this matter, I was contacted by Rosetta Photshwane from MTN about their HVRC not recognising my payment for job card *** for an LG G3 device. <br> I was sent an incorrect job card number *** which I made the payment for. <br> I sent this particular person some proof of payment as she insisted despite the fact that I had not downloaded the receipt after making my payment via online banking. However, I made unnecessary means to retrieve it. <br> She takes days if not a week to respond to my communication and nothing seems to be done to assist me with the issue. <br> I wouldn't go to such lengths to get a broken phone that isn't even mine. <br> Unacceptable service, no customer care at all.
