So, Mr & Mrs Ward are paying £796 interest on their £38,000 of debt. That sounds reasonable so far: a mixture of credit cards, store cards and a few grand from a doorstep shark would average out at about 25% pa. And it's true to say they would be better off if they could get a proper loan and pay all those off.
The next bit is simply a blatant lie: how could they possibly be "debt free after 60 months"? £307 X 60 = £18,420 without any interest at all.
