It's been nearly two months (next week it'll be 2 months) since I got an email from the Doctoral School at a UK university telling me that I got the place and funding. After 4 weeks of waiting, I emailed them to ask when the letter would be sent out but they gave me no specific answer. Also by chance I learned that someone already received their letter nearly 4 weeks ago. I'm very worried and just wondering how long everyone had to wait to get their offer letters. And should I contact them again about it?
