Barclay Credit card offered 0 % in 18months financial to purchase my laptop. After 18months passed I could n't paid off, they charge me interest close to 30 % based on original purchase price retroactively. Suddenly I saw close to {$1000.00} interest charge over {$3500.00} laptop. They claimed " Deferred Interest Financing '' in written in the contract but not clearly explained at signing. I thought my interest will e charged on unpaid part after 18 month promotion is over. XXXX time i saw " Deferred Interest Financing '' in the communication was 5 month later email after I signed. Even that email, it was very graphically miss leading not clearly explained what exactly mean by " Deferred Interest Financing '' under fancy graphical " New Tool '' interfaces.
