Data refill a **** and terrible service

I subscribed to the auto data refill feature a few months ago. It became something I did not want and I cancelled the feature 2 months ago using *135#. I never received a confirmation but thought nothing of it. This week with 20mb left I thought I will buy data in the morning. At 1 Am my data was auto refilled while I still had the 20mb and my account charged. I logged a complaint with vodacom ref number ***. When I called back this morning to find out why the escalation was closed I spoke to such a rude consultant who was not willing to assist me at all. The first consultant I spoke to on Tuesday was very helpful and told me to buy my own data anyway which I did.
