Bugs & human mistakes everywhere
Platform bugs, system mistakes (promo code not work, consolidated multiple invoices and rent cannot be chosen and paid together), human mistakes and delays (team is unwilling to take initiative to help, passive and with slow and poor manners, scheduled payment is unable to be settled per instructed date and time without notification to me or the registered payees) throughout the whole payment set up and payout process. The poorest payment gateway causing total frustration ever used in life. Totally disappointed!
