Vodacom *****ing my airtime

I am a pre paid Vodacom customer which is not suncribed into any services and my out of data bundle spending limit is set to R0.00. But my airtime just dissapears and frequently get a sms that says the following "You've used out-of-bundle data to the value of R10.42 on ### ### #### so far this month." So currently I've been trying to get hold of customer support to assist me, but its an impossible task as I always end up with a chat bot. I ask this bot for a human to make contact with me as this bot keeps telling me "one of their consultants will contact me shortly" as I am still waited to be contacted. I went to the Vodacom store to see if they can help me. Logged a call and got ref nr that support will contact me shortly. "Your query has been escalated to one of our Solution Experts. Your ref number is: *** Visit www.vodacom.co.za/app from your phone. Thank you, Vodacom" BUT still no one has contacted me and they just keep *****ing my money.
