Absolute NO Customer Service

I called 111 Customer Care to get clarity on how 800Mb data could be used up in less than 5 min doing online banking. My 1st call was answered in 2 min of waiting and cut off within 30 seconds. I received a call back but could not hear the operator and was cut off again. No return call. I called 111 back - waited for 9 min before getting through to an agent - explained that I was cut off on my previous call. I had just started to explain the main reason for my call and was cut off AGAIN! - in less than 1 min. No return call. So, data finished without reason - PROBLEM NOT SOLVED. Now it is changed to a complaint! Will this complaint be handled....? All I know is that being a Vodacom contract customer for more than 15 years this is the last straw. Not even the Vodacom App is available - No surprise there...
