MTN not fixing or updating on progress on business client phones

<p>MTN, I have a business phone that was given to me by my place of work. They have many other contracts with you. At the end of May I handed in my then 3 month old Samsung S6 Edge for repairs, as it has become unusable because of some issue with the buttons and or software. <br /><br />Since then I have however not had any feedback regarding the progress on the phone or what the resolution would be. This despite numerous calls to our account manager at MTN. Could you please help us out to get my phone repaired/replaced and back to me as I need it to perform my duties at work.</p> <p> </p> <p>Can someone please contact me and find out what the problem is with the fixing of my phone.</p>
