So I topped my oyster up online on Saturday and selected my correct station, I went through all the pay screens fine then got to the end and it stated order error and that I have to pick it up from London Bridge as they already owe me £2.50 for a refund, I have since been to London bridge and it hasn't added my top up. The money has left my account. I have had no confirmation email so I don't know what has happened would I be automatically refunded after a few days?
