No device and no call back on upgrade!

<p>I recieved a call from a sales agent about my upgrade that was due more than two weeks ago.I performed the upgrade and still have not recieved any update or the device.</p> <p>I then approached MTN over thier webiste regarding a second upgrade on the friday they had a special for 50Gbs per month on select contracts.I logged a service ticket ********** 5 and recieved no service once again.</p> <p>Honestly not happy being an MTN customer, they are only concerned with sales,service doesnt matter...</p>
