FAQ
Q: Bwanji musankhire ife?
Yankho: Tili ndi timu akatswiri, ntchito ndi kuyendera.
Q: Kodi nthawi yotumizira inu ifika liti?
Yankho: Nthawi zambiri zimakhala masiku 5-10 ngati katundu zili pa katundu.
Kapena ndi masiku 15 -20 ngati katundu si ali yawo siikupezeka, malinga ndi kuchuluka.
Q: Kodi mumapereka zitsanzo ? ndi zaulere kapena zowonjezera ?
Yankho: Inde tikhoza kukupatsani zitsanzo zaulere koma ndalama zotengera katundu.
Q: Kodi malipiro anu ndi wotani ?
A: Malipiro<=1000USD, 100% pasadakhale. Malipiro>=1000USD, 30% T/T pasadakhale , ndalama zonse zisanatumizidwe.
