On the 16 July 2023, I purchased a shoe. On 18 July 2023, it was delivered and was the wrong size. Onedayonly acknowledged receipt of my email on 19 July 2023 and requested photos of the item. On 21 July 2023, they once again requested photos of the item. On 24 July 2023, they sent an email to collect item. On 2 August 2023, they sent an email to confirm that my bank account will be credited. No apology, no communication to admit they their blunder and was wrong, no request to check if I wanted another pair. You cannot call them telephonically. Their customer service sucks. Deleting the app and no further purchases will be made. Disgusted.
