I bought a ring from a well known jewellers in their sale in December. Although they measured my finger in the shop, the ring was too big so they said they'd order it in one size smaller. The shop assistant said their policy was to let me keep both the original ring and the new ring and let me try them on for size at home. I had to pay a refundable £20 deposit to hold both rings.
So I decided which one was the best fit and returned the other one a few days later. The shop assistant took my card and said she had refunded the £20 deposit. When I got my bank statement a few weeks later, it turned out that she'd accidentally charged me an extra £20 instead of refunding the deposit. So now they have overcharged me by £40.
I haven't been able to physically get to the store this week, so I emailed customer services with an explanation of the problem, a copy of the relevant parts of my bank statement and the receipt for the ring exchange where you can clearly see I've been charged another £20. That was over a week ago and I still haven't had a reply, despite sending a follow up email to ask if anything had been sorted out.
I'm going to go into the store next week but I'm worried that they're going to try and keep this money. I met the store manager when I went in there to change the ring and he was very difficult - he clearly wasn't happy that they were honouring the sale price when they changed the ring, even though the sale had finished and I'm worried he'll try and hold on to the £40. I don't have the original receipt from when the ring was first purchased. Either the assistant took it when I changed the ring or I've misplaced/thrown it out with the Christmas receipts. I do have the receipt from when I changed it though.
Any advice on this would be appreciated.
