Vodacom - To good to be true!

On 24th February I called Vodacom customer care to cancel a prepaid number I have with them, but do not use. The consultant who was actually quite brilliant sold me this amazing deal because "Vodacom wants to reward their loyal customers" I've been a contract holder since 2002. After accepting this deal, which sounded to good to be true, the consultant told me that I'd be receiving notification from Vodacom to confirm my upgrade. However, after not hearing from Vodacom since then, I called them earlier this week just to be told that there was no deal on my records! Shame on you Vodacom for misleading your so called "loyal" customers.
