Has anyone had trouble with NETO applying a discount code to an order, but removing it onc[...]

I have a special coupon code customers can apply for free shipping, but it is a one use only code per customer. Sometimes NETO applies it to an order showing a discount, but once the customer enters cc details and pays, NETO realises customer has already used this coupon and charges correct full amount.

Customers experiencing this issue are getting really angry they are shown a discounted price, then once they click pay and cannot go back, NETO charges them full amount. Some customers try to double dip, but others just do it not realising they've used code on past order.

It sounds like that behaviour is by design. If customers aren't logged in, then as they enter the coupon code Neto has no way to know if they've used it before. During checkout (by matching either name, email or card details), Neto is suddenly realizing that the coupon has previously been used by that customer and updating the price. That's exactly what it should do.

 

I can't see how it could really work any other way. Your only options are to remove the once-per-customer limit, force customers to login before checkout, or more clearly remind them that the codes are single use.
