Very poor service

<p>In December 2016 we had taken out a contract for tablet with vodacom and then decided to cancel the tablet was then fetched by vodacom I'm order for the return to be made. However the cancellation was never done when we contacted vodacom they say that they have not received the tablet but we have proof of the courier picking it up. I am being harassed by automated calls from vodacom for late payment on this at least 8 times a day and receive calls after 8 at night for this also when contacting vodacom a gentleman by the name of Kingsley tried to assist but asks security questions that don't make sense and when asked to explain them he says that he doesn't know but we have to be quicker as he doesn't have time for this. I then requested for his supervisor who's name is Dino to contact me by the end of the day it has now been 4 days and I have recieved no contact from him. Very disappointing </p>
