Setha izikhumbuzi zangokwezifiso ukuze ugcine abahambele umcimbi wakho benolwazi lwakamuva ngemininingwane yomcimbi. Manje usungakwazi ukuthumela izikhumbuzi ezizenzakalelayo kwabahambele umcimbi wakho ngaphambi kokuthi umcimbi wakho uqale. Ungakwazi futhi ukwenza ngokwezifiso izikhumbuzi zakho ukuthi zithunyelwe noma nini ngaphambi komcimbi, futhi ufake noma yiluphi ulwazi olwengeziwe ofuna abahambele umcimbi wakho babe nalo.
