PayJustNow worst service offered please dont use

I tried to make a purchase instore using payjustnow and the app refused to connect to wifi code instore. I tried to contact us and got still no response. This is the most shocking and awful service as they dont respond to emails and the contact us doesnt ever respond either. They need to do a away with payjustnow and retailers should use payflex, never ever had an issue with them. We also travelled a distance to make a purchase and returned without anything as payjustnow refused to work. This is the worst service and needs to be replaced with a better service provider
