Predatory billing practices Vodacom / Rewardsco

I am not sure if this is the responsibility of Vodacom or their dealer, REWARDSCO CONTACT CENTRES(VODDIR).

I have had the same experience as the review at https://www.hellopeter.com/rewardscocom/reviews/additional-charge-which-was-not-agreed-to-and-then-you-cant-get-hold-of-them-***# (Although I have not been offered a refund despite requesting it after calling Vodacom customer service).

I renewed my Vodacom contract and an additional 3GB was included at no extra cost. I did not request this to be included - it was positioned as a bonus. After three months they proceeded (without confirmation or communication) to charge for this data under the line item "T&B Bonus Data 3GB 25% Disc" which had the effect of significantly increasing the monthly bill. I would recommend checking your Vodacom invoices for similar added charges which may have initially been presented as bonuses / free extras.
