Poor upgrade service

Dear Vodacom. I am a customer for the past decade and yet in spite of the expensive contract charges i still stick with you. It is very sad to say that your online and telephonic upgrade service is very poor. I did a upgrade on monday (11/12/2017) and was told ill recieve my device the next day. Well today is thursday(14/12/2017) and still no device soo i called them just to find out that the device will only be released today. Please remove the next day delivery of your web site and i expected alot better service since people like me ensure people worki g for you can be paid every month. Very upset and will be moving away from your services a.s.a.p. you realy need to get your act in order
