Upgrade gone wrong

<p>I am beyond upset! I did an upgrade online to the macbook pro 500 mb deal. I thought it was a great deal. Having used mtn online before, I expected two deliveries. First delivery is usually the modem and sim card. Check. I got that. The second delivery never arrived. So I checked my application to be sure and it shows I app**** for a macbook air and data. Fine. It's not the end if the world. Having not heard from the call center, I called to check where my delivery is. </p> <p> </p> <p>And low and behold! According to the system I am not getting a device. No one can answer me why my billable amount is so high for data only. I requested to then cancel my contract. Twice. Twice a supervisor was to call me. I tried calling this morning and the call centre was offline. This is not the service I'm used to. I was this sorted. Fix my contract or proceed with my cancellation as requested on a recorded call. </p>
