Reduce purchase Pay 4months if already had monthly installments?
Hi, I Am wondering how Can I pay off a "pay 4 month without interest" if I already have some monthly installments? I mean I bought something for £229.00 to use the 4 months pay in November. I paid back £120.00, but I still have a balancing for £229.00. But my £69.00 monthly installment what I already had, before I used the "Pay 4months", has been reduced now. 😔 How Can I reduce only the purchase for £229.00 and keep untouched my monthly installments, please? Thank you for Your help in advance.
