In mY 2016 i bought a PC from littlewoods, 156wks. i asked them today that i wish to pay my balance in FULL and enquired about interest refund, I was told NO refunds because the item was taken out on interest bearing terms? I asked them where on their T&Cs it says that items on interest bearing terms will not be interest refunded if paid back early, they said it doesnt, so explain to me WHY i am not entitled to a refund then??(2 years interest taken off balance)

I purchased a computer may 2016 from littlewoods. The £2,200 price was spread over 104 weeks so total was £3,500!!!! Now march 2017 and I want to pay in FULL but they offer me no reduction in interest??? Is this leg?
