Disappointed, because responsiveness was low
I found the billing and payments process to be slow in response. My queries about an invoice correction took several days before I got any update. The people I contacted were able to eventually address the problem, but the back-and-forth communication felt drawn out and inefficient. The actual payment process itself worked as expected once the issue was corrected, so that part was fine. However, the lack of prompt responsiveness left me feeling frustrated during the whole experience. Overall, I think the responsiveness could be improved to avoid these delays but the system handles the payments as intended once everything is clarified.
