Vodacom selling specials under false impressions

Be very careful when you upgrade before your contract end date and you get another contract number as special linked to the number you are upgrading. We upgraded on one number which the original contract started years ago in December. So in August 2019 they had a special contract for airtime only which was linked to this upgrade. What they didn't tell us is that the special for the new number, is only 24 months, thus ending end August 2021, but due to the original linked number contract end date being end December 2021, the new number contract will continue also until the end of December, but we will be billed the normal fees and not the special fee for the remaining 4 months until we can cancel it for end of December. This is their way of forcing you unknowingly into a contract at a higher fee than what you think you signed for - they keep quiet about that "linked end date story"
