Vodacom offers false deals to keep customers

Vodacom retention department offered me a deal when I wanted to leave vodacom in October. The deal offered included a discounted 10GB data bundle monthly deal on top of my monthly plan as incentive to make me stay at Vodacom and renew my contract. However after the first month this was removed without notice, I had to call to re-instate it for December. After looking at the latest invoices and debit orders it seems Vodacom has removed the bundle again. This after being promised it won't happen again. This is unacceptable, I will not phone every month to re-instate a deal that was offered to me. If this is not re-instated I will lodge a complaint with the Consumer Ombud for being falsely entrapped into a deal again with Vodacom when you offered me a deal that you are not fulfilling monthly. You are breaking the agreed upon terms with me and are in breach of our agreement. If not corrected I will ask for termination of the agreement based on this breach and I will take my business elsewhere. Fix this once and for all and give me the deal that you promised me to make me stay a customer at the ****test network provider in SA.
