Cell C
No ABSA Notifications

I ported to Cell C from 8ta (an improvement. ) Unfortunately I cannot receive Notification SMS's from Absa. All Other banks come through. If I change my notification number to mnet, they come through immediately. Cell C tells me it is ABSAs problem and ABSA says it is cell C's problem. My feeling is that the problem is cell c's as I receive the notifications on other networks. Can you please help
