No support from SAGE

SAGE refuses to fixed the online access, Clients cant add VAT to there invoice because SAGE system is not working, They blame my computer but I have done that on 7 computers and still the same issue, everyday they give you a new ticket with the same issue, and you have to explain to them what is the issue, They don't provide you with feedback, only they are investigating the issue, This issue has been accruing issue and its not been resolved, how may times do you have to provide the same issue until its resolved, I will not recommend them as they are the reason my clients is NOT SARS complaint
