OZOW not a good payment gateway to use !

Made a booking on Emirates using OZOW payment gateway. Payment went off my account but when returned to Emirates showed payment failed but payment went off my account. Online chat non existent, whatsapp robot no use, phoned - no answer ! Yet, 2 payments of over R16000 went off my account both payments "failed", my bank confirmed payments deducted ! Who are now going to be held liable if my clients lose the extra's I booked for them as only 6 available????? Not the 1st time struggling with OZOW, in future, will not use any website using them as a payment gateway as they clearly have issues with their portal and we as the customers are left running around trying to sort out the mess THEY caused !!
