FAQ
Umbuzo: Kungani usikhethe?
IMP: Sinethimba lochwepheshe, isevisi kanye nokuhlola.
Umbuzo: Singakanani isikhathi sakho sokulethwa?
IMP: Ngokuvamile kuyizinsuku ezi-5-10 uma izimpahla zikhona kusitoko.
Noma kuyizinsuku ezingu-15-20 uma izimpahla zingekho sitokweni ngoko kayo
Umbuzo: Ingabe uyahlinzeka amasampula ? ingabe imahhala noma ngokwengeziwe ?
IMP: Yebo, singanikeza isampula ngenkokhelo yamahhala, kodwa izindleko zezimpahla ziqoqwe.
Umbuzo: Ithini imigomo yakho yenkokhelo ?
A: Inkokhelo<=1000USD, 100% ngaphambili . Inkokhelo>=1000USD, 30% T/T ngaphambili ,ibhalansi ngaphambi kokuthunyelwa.
