bad service

I am trying t solve an integration into Xero banksystem issue since 25 March 2024, finally because Xero contacted them Tershia made an appointment and insisted on 11 am today which meant for me rescheduling my whole day and then they do not show, half hour later I get an email that she was understaffed while she insisted on the meeting at that time. she asked to meet another time today and immediately send her a reply. half hour later I am still behind my computer waiting for a reply from her. This is so unprofessional, like we are all sitting behind our computers waiting for people to respond, we have a business to run which does not include sitting on our computer all day!!
