FAQ
Umbuzo: Kutheni ukhetha thina?
A: Sineqela leengcali, inkonzo kunye nokuhlola.
Umbuzo: Lide kangakanani ixesha lokuhambisa?
IMPENDULO: Ngokuphangaleleyo ziintsuku ezi-5-10 ukuba impahla zikho esitokhweni.
Okanye ziintsuku eziyi-15-20 ukuba impahla azikho esitokhweni ngoko
Umbuzo: Ngaba uyabonelela ngeisampulu ? ingaba isimahla okanye yongezelelweyo ?
A: Ewe singanikezela ngesampulu simahla, kodwa ixabiso lomthwalo liqokelelwe.
Umbuzo: Ithini imigaqo yakho yentlawulo ?
A: Intlawulo<=1000USD, 100% kwangaphambili. Intlawulo>=1000USD, 30% T/T kwangaphambili ,ibhalansi ngaphambi kokuba ithunyelwe.
