No customer service from Sales Department

<p>If I could give a -10, I would do it in a heart beat. On 19 Dec 2016 I left a review that your Sales Consultant Glasson Markham assisted me and sent me the wrong phone. After many attempts I got sorted on how to get that incorrect phone back to your offices. I had to take it to the service store in Centurion for collection. What my issue is now is that your Sales consultant Glasson Markham still has not even bothered to phone me back, after many messages and emails that I have left nobody has bothered to phone me back. WHAT THE HELL IS WRONG WITH YOU?????????!!!!!!! Do you know how to assist customers telephonically???? I want my phone!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I want someone to phone me back in the next 24 hours, not promising anything that is not guaranteed, but giving me the service I deserve as a customer that has been with MTN now since May 2000. GET YOUR ACT TOGETHER AND START PHONING ME BAC****!! YOUR REPUTATION IS NOWHERE, YOU ARE LOsING CUSTOMERS AND I WILL BE 1 OF THEM!!!!!!!!!!!!!!!!!!!!!!!!! I phone the sales department, but all of a sudden only get through to your Durban Branch. I asked the last consultant to put me through to a manager and she said she can send Glasson and the supervisor a email to phone me back. THERE IS NO F*&^%%G GUARANTEE THAT YOU WILL F*&^%$G PHONE ME BACK. I just realised that I can't complain about this terrible service as there are no F*&&^%g service.</p>
