No Sms Notifications for Debits

I don't really have a complaint regarding service or anything, I have been banking with SB for the past 10 years & I have no problems at all with the service, but I am a bit frustrated with the SMS notifications option. I called in about 3 months ago to as if I can please have sms notifications sent to me whenever money gets debited from my account. I was told it was gona be set up & from the new month I should receive my sms's. Its 2 months already & last month as well as this month I have not had any notifications sent to me. This is a rather frustrating situation for me because its a real inconvenience to keep checking my statements to see which debits have gone off. I called last month & I was told that it is set up on my account, maybe there was a problem with the sms's which I find hard to believe, given that many of my family members bank with Standard Bank & they all receive notifications when money leaves their account. I dont know what the problem is with this because everything else works fine. Can someone please let me know whats going on with this. Its very frustrating to keep calling in & being told the same thing over and over again.
