I have been writing to Wonga continuously for a few months now trying to get them to agree an installment plan but they dont even acknowledge my letters which i have sent recorded delivery. I than got a letter from Barker and Lowe. I sent them a letter and it was returned unknown at this address. Today i have received a letter from Sherwins saying debt is now £1400 on original debt of £400. Who are Sherwins, are they just Wonga under a different guise. Cant get anyone to respond but i guess for them it just keeps things going longer so they can keep piling on the interest. Any suggestions?
