eBucks and SmartInContact problems.

I have been trying to get our company eBucks account working properly since 2 November 2023. When I try to buy something on the eBucks shop the SmartInContact message does not come through. Using their secure chat on the app gets me sent from pillar to post with no result - they continually blame it on network issues. However SmartInContact works on the other business account I have on the app - how can it work for one and not the other. I have been told the issue was escalated to the technical gurus and they would contact me in about 48 hours - this was on the 7/11. I'm still waiting. Very unimpressed.
