Ok, so "loan Amount" got up to £1480 from the original £400, that was the 1% interest per day plus the fee for attempted payment at $5 per day.
Proposed an arrangement, original plus interest, but no fees for doorstep collection, which as you know never happens, late fees and no way I was paying for the attempted debit card fees, because I already advised I had a new card so stop trying!
Happy to say they accepted the offer and I am now done, done done with these guys.
Have loans with many other companies for my sins, and all have been VERY helpful with repayments plans, some over 6 months.
My advice, stick to your guns, ignore "threats" etc, do everything in writing, not over the phone, and in most cases (i have loans with 12 payday companies) they are reasonable, even if you pay a small token amount it helps.
