Hello Phil

That should not be possible. If the user is using the same email address, he's considered the same customer. So, if you see a customer that used this coupon 4 times, we may have a bug (I'm not capable replicating on my end, by the way).

Please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third party. 

You can write credentials here just check Private Reply so nobody can see them except us.

Not really, Phil

Can you please tell me which lesson the customer booked, what customer is this, and provide me a temporary wp-admin user (administrator), and I'll gladly take a look and see what's going on.

Please note that this is a public ticket, so make sure to enable the PRIVATE response when posting credentials.

I need to take a look at this, Phil, since one customer should not be able to use the same coupon more than once, if that coupon is limited to 2 uses per customer.

I can't see Amelia settings with Amelia Manager, so I will need admin access.

We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third parties. 

You can write credentials here just check Private Reply (like you did), so nobody can see them except us.

Thank you, Phil

I will take a look at that other ticket right away.
