Hi I've had a number of problems topping up Oyster at Peckham Rye, because the machine was out of service and they don't do Oyster transactions at the window. So was told to find a local shop to top-up / load a season ticket on to my Oyster card, which wasn't convenient. Plus I'm not happy paying by card at the local shops and am not sure if they have the facility anyway. Can we get another machine at such a busy station or be able to buy Oyster products at the ticket windows? Many thanks Chris
