iKhokha Settlement Time issues

As a Resraurant owner we rely on efficient fast Card transaction settlements, especially in todays economic climate. iKhokha promised faster settlements when dealing with a client who banks with FNB, like we do. Our business purcaheses are dependant on early daily settlements to aquire stock on a daily basis. These settlements seems to have their own time schedule without any consistency though Settlements should usually be paid in before 9am daily, with some days as early as 7am. Other days settlements happen after mid day, or not at all, being settled only a day later. In one instance we had a three day delay. We cannot operate with this inconsistence. Contacting iKhokha support also seems to be a futile exercise as they cannot give any reasons for delays, speak in a dismissive tone to us as the merchabt or do not respond to a live whatsapp line support enquiry. Communication in this company between merchants and support is less than desired. We have never had any settlement issues wiith previous service providers, and unfortunately it has come to the point where we are weighing up the pro's and con's of staying with iKhokha as our card payment service provider
