Settlement letter required urgently

I have a wonga account which was referred to Blake. I have called called Wonga on Tuesday to request for a settlement letter for my account and my call was transferred to Blake as the account has been handed over to them. I spoke to a lady on the phone who advised that I should receive the letter within 5 working days.

I made a folow up call today as I need the letter urgently as I have requested for assistance from another company to assist me with repaying the funds and requires a 'SETTLEMENT LETTER' to process funds.

I called in the call centre and nobody seems to know what I'm talking about, I'm being asked to make payment in order to receive the letter and I had already explained that i dont need a a 'Paid up letter' I need a Settlement letter. I think i have wasted my time by calling in beacuse theere was no record of my phone call on Tuesday, the guy i spoke to on the phone made me wait for 10 minutes and hung up on me without even explaining.

Can I please receive the letter ny close of business as I urgently need to make payment, I have delayed and I'm about to miss the timeframe that was set up for me
