DATA ISSUES AND POOOOOOR CUSTOMER SERVICE

My data kept reducing on my phone. I called the vodacom customer centre and spoke to lady, I explained to her that I was driving and that my data was reducing. She than argues with me about the settings on my when I explained to her that the settings she is wants me to check are off. I was to speak to a supervisor or manager she proceeds by saying they are working from home. She then puts me through to a colleague as she couldn't assist me, and was very rude i must add. Her colleague try's to assist me then tells me that that cause of my data reducing is browsing the net, when I try to explain to her that I am on the wifi she tells me I am hot spotting someone and hangs up the phone.

What ******* service is this?????????????
