Luxury Bus HCMV To Can Tho?

Hello:

I would like to know if there is a luxury bus company from HCMV to Can Tho, and Can Tho to Chau Doc?

Luxury = safe drive, space, reliability, bus departing on time ....... toilet .....

If yes, where can I buy the ticket? Online?

Thanks

ps: perhaps same standards as the luxury bus in Mexico (or close)
