Paying for Nonexistent Services

I have international roaming activated on my cell phone account, yet in my last business trip this stopped working (leaving me at risk should there be any emergency). As I returned home I was welcomed back to a blocked cell phone account, which I was never notified of, that nobody can unblock. Eventually , I was able to log the unblocking and highly stress that this number is used for business and it is an urgent request. On the 03/04 I was promised feedback with the unblocking to be completed by the next day. After receiving no feedback I called again to be told I was misinformed and that this will take 7 days and I cannot expect this to be faster. I have just switched to vodacom and I am regretting this decision.
