Vodacom *****ing Data/Money!!!!!

I have been a customer at vodacom for over 7 years, Each year they just become more unprofessional, Their service is not what it used to be, And they are the most expensive with data and then what they do they ***** that from you as well....

In 3 Months time, every time I load data on my mobile (Never less than 1GB) my data will be depleted after several minutes, without any background app refreshments, Automatic updates nothing is Switched on or enabled, I logged 2 Calls with them already and still haven't received any feedback, I'm so disappointed in Vodacom, I have an Iphone 7 Plus which I pay R930 per month, Never was any payment late or refused, everything always on time but when you need them to solve any of their own Problems it always becomes an issue, After this Contract I will never do Business with Vodacom ever again and will recommend them to absolutely no One!!!!! Welldone Voda*****S you've done it again!
