Vodacom service is very disappointing

<p>I did an upgrade online in December 2016 to an S7 edge. The phone was delivered to me but within 7 days it had problems of overheating and freezing. I called the vodacom upgrade department to collect the phone. After 9 days they came and collected the phone and they told me I will get a call after 3 days to notify me of the reversal of the upgrade so that I could do a new upgrade. Till today I haven't received a call and the upgrade haven't been reversed and which means I can't do another upgrade. Not forgetting that I'm paying for the device that I don't even have on me. For the last two weeks I've been calling the vodacom upgrade department and all of them are telling the same story 'the person who is working on my account will give me a call back' which she never did. I called all vodacom departments to assist me in this matter and non of them can assist me. And now I can't even get through to the upgrade department. Whenever I get through all consultants that I speak to hang up the call as soon as I explain my problem. It really feels like vodacom is a FLY BY NICE ORGANISATION THAT TOOK YOUR MONEY AND DON'T WANA SPEAK TO YOU ANYMORE. I'M AT THE POINT WHERE I'M JUST GONA CLOSE THIS CONTRACT. I'M ACTUALLY DISGUSTED WITH THE WAY VODACOM HAS TREATED ME. </p>
