Account Softlocked after payment

This morning I received an sms regarding my account that it's going to be soft locked,this is regarding this message / sms I received - Vodacom Balance Notification. MANATORY ACCOUNT LIMIT REACHED SUBSCRIBERS SOFTLOCKED.I really dont understand why wasn't i told when I went to pay the R1750 that it was going to be locked because I reached my limit.Not I can't use my phone and I have a baby that I don't live with and how is my mother supposed to call me if there's anything wrong with the baby. Now I get told I should be paying the R1500 or the R500 to reactivate the phone.When am I expected to get this money from because I work with a budget here, I don't have money lying around anytime.This is an inconvenience really and unfair.So I now have to stay without a phone.Why don't we get told these things from the on set?Will wait for month end to cancel the contract and pay the remaining phone amount, I'm really disgusted.
