Vodacom takes your airtime and then blames you

Yesterday on the 12/03/2018 in the morning I bought airtime to load data from my banking app. It all went smooth with no surprises...like it usually goes...then in the afternoon I loaded some more airtime to buy data and I received the free airtime but not the R20 I loaded. I then proceeded to phone customer care and then they told me I have subscriptions to some things I never heard of before and that never deducted monies before...then I phoned again and the lady was extremely rude and with her tone insinuating that I do not know what I am talking about...she then proceeded to try and explain how I can maximize my phone but she had no clue how my phone operated and I could tell she was getting annoyed with me... then at the end she just said I have subscriptions and that they took my airtime....first time ever since I have been with Vodacom. I have been with Vodacom since 2000 and I have had this same number for almost 5 years....I am highly dissapointed that after all these years they treat a.customer like this...my whole family is on vodacom but not for very long and the same goes for me and my friends...
