FAQ
Mubvunzo: Sei kusarudza isu?
A: Tine chikwata chenyanzvi, basa uye kuongorora.
Mubvunzo: Inguva yakadii yekutumira?
A: Kazhinji mazuva 5-10 kana zvinhu zviri mustock.
Kana kuti mazuva 15-20 kana zvinhu zvisiri mu stock, maererano ne huwandu.
Mubvunzo: Iwe unopa masampuli ? ndeye yemahara kana kuwedzera ?
A: Ehe, tinokwanisa kupa sample yemahara , asi mutengo wekutakura wakaunganidzwa.
Mubvunzo: Ndeipi mitemo yako yekubhadhara ?
A: Kubhadhara<=1000USD, 100% kare. Muripo>=1000USD, 30% T/T chiripo ,chasara chisati chatumirwa.
Kana uine mumwe mubvunzo, pls inzwa wakasununguka kutibata .
