Salesperson misinformed me and I lost my upgrade

In October, my account was due for an upgrade. I phoned to say that I would be travelling 2 months but wanted to start my upgrade only when I returned. The sales consultant advised that I would lose my cell number if I didn't BUY AN UPGRADE NOW! KEEP THE NUMBER ACTIVE. I told her I need a high level package but didn't want to initiate until I was back.

She told me that I could go on a 2G data only contract for the two months, and when I returned I could do my upgrade. Well, that turned out to be an outright lie.

I came back and I am no longer due an upgrade because it has already been 'processed.' Furthermore, if I migrate I will be paying way above the list price. Also furthermore, I can't get a new phone. it SUCKS and it is an outright lie to be sold products in this way and totally *******.

I am a Vodacom client of 15 years, and I am just about to sign another contract with a high level spend as I use this phone also for business. If this isn't resolved swiftly to give me back my upgrade option, I will ditch Vodacom permanently and go with another supplier who aligns their sales principles with the law.
