Unable to perform transactions on any Android phone

Today we were unable to perform any transactions on any of our Android phones as the IKhokha application keep-on prompting "iKhokha has stopped". Called iKhokha's Customer Services, who has initially advised that we have the incorrect version of the application and/or that we have to restart our phones. After following their advice, we were still unable to perform any transactions and we were still getting the same message of "iKhokha has stopped". Again phoned iKhokha's Customer Services, who then advised that they have a server issue, which will be resolved within the next 15-20 minutes and that they would communicate resolution via e-mail. Unfortunately that never happened and we are still experiencing the same problem. Fortunately these calls were recorded and can be verified. To say I am disappointed, is the understatement of the year - "pathetic" is to put it very mildly! Businesses already struggle with the impact of Covid, but with these inefficiencies businesses have to suffer further. We now have to consider moving over to Yoco as this inefficiency is not sustainable for any business. Poor!!!
