Data Bundles/No Data Bundles

About 3 months ago I upgraded my cell contract to Smart S with an Iphone 6. I have had the Iphone 5 before, so I knew what to expect. But for the last 3 months I have been struggling to activate data bundles on my phone. I tried using the *111# function, the Vodacom app and eventually the Vodacom website. All with the same results. I purchase the Bundles, and my account gets billed, but then the Bundle does not get activated. I have to phone the 111 helpline and hold on for 30 minutes every time, for them to run around and find out what the problem is. Then the bundles get activated. Yesterday it was again the same thing, when I phoned the 111 number they said I must wait 7 hours because their system was over loaded with month end. I waited 8 hours and phoned again. Now they tell me I have purchased too many bundles. I must wait till August. How can you call this service? They are eager to bill me, but please wait for your data bundle... I have asked on numerous occasions for Vodacom to look into why this is a problem since my upgrade, but no joy
