    FAQ

    1. Kuthekani ngexesha elikhokelayo lomyalelo wobungakanani bobunzima?
    RE: Ngokuqhelekileyo sinokulungisa iimpahla kakuhle kwiiveki ezi-2 emva kokufaka iodolo, kwaye ke sinokubhukisha indawo yempahla kwaye silungiselele ukuthunyelwa kuwe.

    2. Kuthekani ngexesha lokukhokela?
    Impendulo: Ngexabiso elincinci, iimpahla ziya kuthunyelwa kuwe ngaphakathi kwe-1-3 yeentsuku zokusebenza emva kwentlawulo.
    Ngobungakanani obukhulu, iimpahla ziya kuthunyelwa kuwe ngaphakathi kwe-3-7 yeentsuku zokusebenza emva kwentlawulo.

    3. Ngaba kukho nasiphi na isaphulelo xa sifaka iodolo enkulu?
    RE: Ewe, siya kubonelela ngesaphulelo esahlukileyo ngokweodolo yakho.

    4. Ndingayifumana njani isampuli ukujonga umgangatho?
    RE: Emva kokuqinisekiswa kwexabiso, unokufuna isampuli ukujonga umgangatho kwaye singathanda ukubonelela ngesampuli.
