Quick update!
I called the number given to me by my branch, and over an hour (yes HOUR) later I get through to an indian woman that promptly tells me I need to contact my branch quickly gives me the branch phone number and hangs up without even a 'bye'!
So local number, call it and let it ring for 5 mins, a quick search on google reveals the number is a 0870 number which happens to be the same for all branches...
I call it and the first thing it asks me for is a 16 digit card number (the very card the cash machine had retained).
Eventually I get put through to a queueing system and another indian lady answers who then has to put me through to another department. Fortunately I got put through to a very nice english girl who went out of her way to help me and ordered me a new card. She admitted the card was swallowed by the network problems they suffered on tuesday and that a large number of other people also had their cards retained.
I now have to wait 5-7 days for replacement card which is another inconvenience as the problem of me not being able to access my account for 1 afternoon has now expanded into a whole week!
