PAY MORE FOR LESS

I have app**** for three business contracts (data only)(new account) at Vodacom Business in the first week of February 2024. At last, three weeks later, the new accounts was approved. It was a very slow process to get the accounts approved. I would expect this process to be much quicker. Nevertheless. Yesterday, after 4 weeks of wait, I again contacted the person dedicated to me, only to be told that the portfolio of the account does not qualify for this contracts. I have app**** for three contracts SIM ONLY 80GB day and 50GB night for R299.00 per month She is offering me now :SIM ONLY + 30GB Data 24 Months @ R 299 PM (R0 + R299 Subs) on 30GB Data Top (60GB day + 30Gb night ) This is much less data for the same price? Can you please explain to my why I can not choose the contract I want to buy? Why do I have to pay the same amount for much less data? I really do not understand this and I do not understand why the accounts does not qualify for my choice of contracts? Please help me to understand.
