Do not stick to agreements made

I took a pay day loan recently but sadly hot retrenched. I made an arrangement with the 'lawyers' to pay off the debt and was told that should they deduct the whole amount i must contact them for a full refund. 2 weeks later after up and down calls to these Blake Associates and Wonga themselves, i get an email stating, there is no refund due to me. So i sent them and their lawyers the email on sunday at 00.51 to ask them to contact me so i can sort it out. Its now tuesday and guess what? Still no call. No phones are being answered, no one has responded to my email as of yet and im now getting tired. They have put me into such a situation. I made the agreement to keep my head above water while i am looking for new work and now im busy drowning. I will be taking this further should i not recieve contact by the end of this day
