MNET delivers LAPTOP without asking for it

At the end of my current contract with MTN, I explicitly specify that I do not want to upgrade to a new device and that I only want I data plan for my current device. MTN delivered a Laptop at my house and started billing me for it. I signed for the laptop before realizing what is going on. For the last couple of weeks I tried in vain to contact MTN on their assigned customer care numbers. You hold on for a very, very long time and as soon as a consultant answers, the call gets disconnected. this happened at least 5 times. I also send an email to the assigned address and received a ref number but there was no other action from their side to date. I do not want this laptop and I need MTN to take it back. The laptop is still in its sealed box. Should MTN go back and listen to the recording of the telephone conversation between myself and their consultant who contacted me with the upgrade offer, they will hear that I DECLINED the upgrade offer to a new device.<br> <br>
