Good evening and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are really sorry to hear about Event aggregator not working properly on your installation. Yikes!
As per your request, I went ahead and processed your refund. It might take a couple of days to show up on your end.
With that in mind, we are always looking to improve our products and services.
As such, if you do not mind, we would like to get a bit more info on your imports.
Using a private reply, could you please provide us with URLs you were trying to import from.
That way we can run some tests on your end.
Finally, no obligation on your end, but if you could also your complete system information using the instructions found in the following link, it would really help us.

Best regards,
