Poor service

My contract with Vodacom finished last December 2021 and ever since I been struggling to put my line on redflex zero or pre-paid so I can take a break until I decide what I want to buy. I was even forced to get another cheaper contract because if I do not get a contract my number will be freecycled and I lose my number. I eventually got a contract of R60.00 (just for airtime) hoping to put my misery to an end but I was fooling myself - they keep on deducting exorbitant amounts every month. I have been sending emails to them but no one replies. I tried phoning and they will tell me everything is sorted but they keep on charging me over R200.00 for the data and air time I do not need - no phone. They won't even give me an opportunity even to be heard by senior management. This is **************** - all my trust and respect I built over the past 10 years right through window.
