Data usage

Vodacom SA how is it possible to purchase a 1Gig top up and within 10min it's finished. All I did was watch a video not even high res. I'm getting really angry at your service! This is the 3rd day where you have ****** me. I did the 1Gig top up 3 times in a row today and every single time this happened. Also I have a 50Gig data package, in this week I contacted you and you told me that I used so much gig in that time frame, within 2 hours 20Gig was gone and I did my usual business, and it never takes this much data while writing emails etc. Before that I purchased a 3Gig data top up and that was even quicker - 5minutes and it was used up. I didn't even download anything!?! I monitor my data usage on the Vodacom app and it is impossible for the data to have run out so fast!! I've been a customer for 20years and now in the time that we need data to run our lives you are taking advantage of us?? Please explain?? I thought you assured us of extra service during this time, it rather feels to me that you are making up your sales with data. Anyone else experiencing the same problem??
