Black Friday website issues - Payment not reflecting

Browsed the website at about 1am. Added items to my basket to buy. Decided to check out at around 9am when the website was down - was given the opportunity to check out and pay for what was previously in my basket. Website extremely slow processing the payment. Payment went through but on the order it showed "awaiting payment" Immediately logged a ticket on the website. Got a response within minutes, send the guy a screenshot of my deduction from my account. Minutes later got another response saying "payment confirmed and manually updated" Received my order yesterday (Monday). Truly excellent service! I was astonished in the response/resolution rate.
