Is my maths wrong? (Shop refund)

Big supermarket near me, closed off its changing rooms during COVID. Went in to buy something important that needs to fit correctly (swimming costume for a pool party booked the next day).

I asked a staff member near the clothing if the changing room was open any more, she confirmed no (I think they're now used as stock storage, you basically can't get beyond any barrier at the entrance). She advised of a 100 day refund policy and confirmed if was okay to buy a few, try them on that day, then refund (with all labels and hangers) the same day.

Bought a few costumes in different sizes (size 12, 14 and 2 different style 16s) along with my £20 ISH food shopping. Paid on a credit card and some vouchers I'd got (think something like clubcard voucher or Asda rewards, a specific £value). Total was £69.

Went back within thr hour (hurrah, 1 costume fitted) and attempted the return at customer service desk. 3 returns to process.

They were:
£9 costume on sale
£10
£20

I expect a £39 refund.

The customer service rep says it is a £39.43 refund that I'm entitled to, because I used a £1 voucher it influenced the refund value as it applies to the costume too.

I asked if the 57p will go back onto my loyalty voucher value, she said no.

What would you have done in that situation? What's a reasonable refund value?

A - be happy with £38.43
B - er, you returned £39 of goods so they need to make it right to £39 value even if it's on a gift card
C - £39.43 refund due back.

I won't drip feed, I'll share here that the customer service desk lady insisted on A. I insisted on B and asked to speak to a manager. Management was called who tried to give me a £38.43 credit card refund then give me a £1 gift card (which I explained was too much).

Aibu?

I think it depends what kind of voucher was used tbh. In Lidl for example if you used a £10 off voucher then they take the pro rate amount off each item. So instead of paying say 2.99 for loo roll you would pay 2.75. Then if you took loo roll back for a refund you would only get 2.75, not 2.99 the value of the item.
Sounds to me like this is what happened. If you used a £1 voucher you have had say 20p off each item. So if the costume was say £10 then you are only going to be refunded £9.80.

Happily expect as they arent usually meant to be able to expect returns on anything that touches private area due to hygiene reasons regardless of whether the label is still on it

My thoughts exactly. Gross 🤮.

I have a friend like you. I dread splitting the bill with her.

Jeez life is too short for all of this.

Anywhere I go now they pro rata a discount voucher on a refund. I assume it’s to stop the people who buy an extra item to get the shopping over x value to get a discount and then just return one but still get the full discount.

it is a bit frustrating when it’s a genuine return but I see why they do it…..
