How can i apply for a job at GameStation in the uk (without actually going in and asking)?

I wanted to send in a Cv by post as they don't have a search and apply option on there site, so i dedcied i needed to try and find out who the manager would be. After phoning all i get is an automated response that starts talking crap than asking me yes or no question. After finally get to the bit about the store i want it gives me the address and opening times which i already knew and suddenly that's the end of it basically one big pointless loop. Then i go onto the chat to a online customer service team member give them a shorter version of this, then after waiting ages she says she cant give out information like who the managers leaving me thinking wtf how am i supposed to get it to the right persons. So those anyone know how i can find out how to get a job without going in which i probably will end up doing. (even better if there are any gamestation managers here in london looking to hire)
