I guess you could look at it this way.
Ordered on the 24th at the retailer, paperwork etc goes to H/O and order placed within 3 working days (but they could have a back log with furlough staff at H/O), so now you are looking at the 29th June, due to the weekend. This would mean its only been 16 working days so far but that's assuming AG placed the order within 3 days.
Anyway, are you trying the shop for information or H/O?
I found the H/O contact number after a quick google search
01925 488400
Let me know if you get better luck with the H/O number as I might be chasing up my wifes clubs in the coming weeks, but I hope not.
Hope they arrive soon for you.
