Refund for Dress still oustanding since December 2023.

I have been trying to get customer services to resolve an issue since December. It is now May. They promise to get back to you in 24-48 hours then nothing. Tracy from Cavendish store has been helpful but does not havw the power to resolve this issue.

Then issue started when I returned items to the Cavendish Store in mid December. Firstly the credit card refund was only processed after 2 weeks which is when I checked the store receipt and online order (which shows which items are returned) and realised that the store had not captured the return of one of the dresses. When I returned the items to Cavendish the store was very busy and the staff under pressure- which is why I believe there was an error on returning my order. After I realised the error I logged a query to the online customer care who told me the store would get in contact- this was not a smooth process and ended up with me having to call the store repeatedly. Tracy did follow up and call me back but the process was flawed from the start. I cannot explain the missing dress on the stock system but being December I can only imagine things can get mislaid. This should not be my fault. I also want to make the customer care aware that after returning the Robin dress Size 8 to Cavendish as it was the incorrect size- I ordered another Robin Dress in a Size 6 which I now have. This order was placed on 18 December after I returned the Size 8. I am a regular customer of Poetry and I would like a credit for the dress I returned.
