BSS B2B Wholesale Solution

Tried to partner with this app because it looked ideal and had good reviews. Being in Australia, we were directed to an office in Vietnam. Had a rushed demo and then we sent an email with one single question. A "ticket" was sent to us but had no content. Followed up a few times seeking an answer or more info. No replies to the emails. Eventually sent one saying will you assist, or should I give up? No response. Very disappointed.
