My husband has had the dreaded letter from the government telling him to shield. This was weeks ago and he immediately registered on government website. We still haven't been able to get supermarket delivery slots. He called Tesco this morning (who I have an online account with) and they've checked the database and told him he's not on the government list. So he's just registered again but we have no way of knowing whether this has worked.
Has anyone else had this problem? Seems like the system is fundamentally flawed.
