Three phone calls today, all recorded messages along the lines of "This is the Mastercard and Visa department of your bank, a payment has been made for xxx...". Shame they didn't think to specify the name of the bank, as if it might be relevant.
They've just realised the search by post code to find out which tier. Adur and Worthing are both tier 2. The website broke before I could search any others.
I’ve received one of those, I don’t think it’s key workers, it said just 100,000 random people when I looked it up. Not looking forward to shoving a swab up my nose, but if it all helps.
