App and online fails to let me complete an order on three occasions. Not my browser, not my system, not cache, not my bank, no other transactions are a problem. 4 people on line and four emails prove that JD's customer service dep't is full of dummies. No-one knows how many other people have issues and therefore buy elsewhere, but if there were 100 a week, which isn't many, that could be £1m+ a year lost revenue. All I get is replies from people who haven't read my emails which have told them I can't order and the reply I just got today was we can't access emails older than today any more, please give your order number. Stupid or what? No number available other than useless 'customer service' which is useless. Takeover, administration, closed stores, redundancies imminent if they don't sort themselves out. '0' stars.
