Never been mad in a long time. Poor customer servi

Yesterday I was recharged with R55 airtime and I had R3 left totaling to R58. I spend R6 and was left with R52.just after midnight I bought R12 combo of power hour and 60mb leaving me with R40. I always receive an sms when my data is almost finished but today nothing whatsoever. When I tried to call a family member I'm told I had insufficient funds and I checked nothing was left. I just called in to the call center and the rude guy force me to admit that I have automatic updates option on and that my updates went on without notifying me. The little knowledge this guy has, he tells me that he can't even tell me if it's my phone's update or application's update and sends me a message to go to vodacare to ask them to help me out and prove me wrong that I have auto updates. I mean really? Simple question...why didn't I get a message like I ALWAYS DO that my data was running out so to make sure I buy more again. I am always telling people that vodacom is the best and have turned people to vodacomites and this what I get for thank you I get? I spend close to R500 every month and have never encountered this airtime disappearance thing. I want my airtime back today and not a day later.
