Vodacom *****S data!!!

This afternoon I tried checking my data, 'service temporarily unavailable' then when it worked I had around 180MB data. An hour later BOOM I have 19MB DATA after my I left my mobile data off and left my phone on charge. No apps auto-updated. Mobile data off. After speaking to the call centre consultant and her supervisor for 45 minutes who REFUSED to lodge my complaint, I feel like jumping ship. I'm so ****ing tired of poor customer services. Your management refused to help! Everyone knows MTN and VODACOM are under suspicion of *****ing data. I ****ing hate this. I want my damn data back!
