Mistaken upgrade

Elitemobile, whom I have never dealt with but somehow had my phone contract details with vodacom, called me randomly to upgrade my contract which had reached its 2 yr expiry date in Dec 2017 (this process has happened 8 times as I have been a vodacom customer for 16 yrs). They proceeded to tell me I qualified for extra data on the same package (Red Premium plus) so it sounded reasonable to upgrade. They neglected to tell me the upgrade didn’t come with a phone upgrade. (I had no idea there were contract upgrades with no new phone as I have upgraded to a new phone each of the previous 7 upgrades). When I finally got back from holidays and got round to enquiring why I don’t yet have a new phone, they claim the “cooling off period” of 14 days has expired and they have to double check the exact phone recording as I am now locked into a renewed contract until 2019 which I cannot change. I find it unacceptable I’m locked into a 2 yr renewal on a contract where I don’t get a phone upgrade and where I was coerced by salespeople right at the end of the year who weren’t 100% transparent about the upgrade. It’s also unacceptable that Vodacom pass my personal details onto agents such as Elitemobile. Is that not contravening the Consumer Protection Act and the Protection of Personal InformationAct? Elite mobile and Vodacom need to reverse this upgrade with no cancellation charges and be transparent in offering the usual upgrade with a new phone.
