The so-called Customer Care team is misnamed: they don't care at all.

After several days of e-mails from a succession of different individuals (never the same person twice!), what I regarded as quite a serious complaint has led to zero action by Lidl. Evidently, it's fine for the shop staff to be rude and aggressive.

For bonus points, despite failing to take the complaint seriously and doing nothing to resolve the issue, some joker called Douglas finished by telling me: "We hope you’ll continue to be a part of the Lidl family and can’t wait to see you in our store."

Well I have news for you, Douglas: after what happened to me last time I was in the store, and after years of consistently sullen service in that same branch, if you're going to let it carry on then you won't be seeing me there again. I struggle to believe you're taking no action, but if Lidl cashiers are allowed to be as rude and aggressive as they like, then I definitely don't want to be a Lidl customer.

Naively, I used to suppose that, if Lidl actually knew how rotten the service was in our local branch, they'd be horrified and they'd step in to sort things out. But no: turns out the crummy service is part of the Lidl package. Thanks, Douglas, for making this clear.
