We had a customer request a return and a refund, we sent a UPS prepaid collection to the house which they were aware of (tracking details supplied etc) and the customer missed the collection.

Customer opened an A-Z claim and then withdrew the claim after agreeing to drop off the packages with the new prepaid labels detailed below

We then said we can send pre paid postage labels so they could drop off the items, they requested post office labels due to the drop off point being closest so we supplied another 2x labels to return the packages to us, again free of charge.

The packages arrived today 04/09/2024 (9:35am to be precise) and we issued a full refund today at 11:59am 04/09/2024.

Customer replied to us stating we had only refunded 291.64 of the 349.97 order stating they would like the 58.37 missing to be reimbursed, I kindly stated to them to wait for the confirmation email from Amazon to state the final confirmed refund balance and that the order status would update once the final balance had been settled, the difference in what you are is seeing and the total refund is the VAT amount and that this would be reimbursed in full once the refund had settled. I detailed all of this to the customer, even with the math to work out 291.64 * 1.2 (20% VAT) makes up the total 349.97 rounded to the nearest pence.

Despite this, it looks like the customer has opened an A-Z claim to recover their 'missing' VAT balance, but due to us refunding the order we have now had an email stating We have closed an A-to-z Guarantee claim of £349.97 on order 'X' because you issued a refund to the customer. No further action is required from you at this time but we have counted the claim against your Order Defect Rate.

Anyone had experience with this refund pattern in the past and any luck on getting the ODR reversed? In my past history I've known despite the information you throw at the A-Z team once the claim is in it's not getting overturned.
