Zestlife - Double Standards

My recent interactions with Zestlife has been condescending, shoddy & unempathetic. Zestlife wants to emulates Banks when charging refund penalities! Zestlife double & triple debit their customers & there's no penalties levied against them for the inconvenience & trouble caused? Can Zestlife not apply the same treatment to it's customers & stop using the Banks as a yardstick??
