Sorry Vodacom

I have been with vodacom for many years having several contracts with them. Last month I upgraded 2 of my contracts which were due for upgrade but neither were eligible for cancelation as the 24 month period has not passed. Both contracts I receive additional data and minutes at an 85% discount. In less than 24 hours after upgrading i called vodacom to cancel my upgrade, they told me that the update had been reversed and my contracts would remain the same till the end of the contract period.

This month my 1 number remained the same but the other number only received the additional minutes and not the additional data, when I called vodacom I was told that the additional data had been 'deleted' and could not be reinstated, I was confused because my 24 month term hadn't yet ended but all of a sudden they are unable to reinstate something which is supposedly in the contract. Vodacom customer care says it's an issue on the retentions side and retentions says it's customer care but it's the same company.

Furthermore I would like to add that when I took out these 24 month contracts I had received additional minutes and data on almost all my contracts at 90% discount, however last year April the discount was cut from 90% to 85% which affected my total bill by R500 per month. This year March vodacom had a tariff increase which affected my bill by another R400 per month and now since the beginning of June yet again Vodacom cut their discount structure from 85% to 80% unannounced which again affects my total bill by yet another R400. So in the space of less than 24 months my total monthly bill has gone up by almost R1300 per month. What does vodacom have to say? Oh sorry as if the sorry is going to pay the bill.
