Inspiron 14 5490, payment cancelled, new order price change

Hi,

I order a Dell Inspiron 14 5490 laptop yesterday (order number  ). My payment got canceled. I need to pay it again. But when I'm paying it today, the price of the same laptop increased from €764  to €913. But I want the previous order with the previous price. I'm really annoyed with the calling service and they are not helping me at all.
