I did know, but I didn't think getting in contact with them would help.. I couldn't extend my loan as I didn't have enough money, and now I have none. Should I call and explain my situation?

Hi everybody I've taken out a few Wonga loans for the past maybe, year or so, and I've always paid them back on time. This time I've gotten myself in a bit of financial difficulty and the repayment date was today. I was planning on calling them after I finished work to discuss what I could do, but they've just gone and taken any money I had in my account! I had £122 to last me until payday and now it's gone! I have £2! What do I do? Do you think if I called them they would give me it back!? Any help with this would be appreciated, really, anything. Thanks in advance!
