Wrong address won 4D first prize

I ordered flowers to be sent to three friends for Lunar New Year. Here is a message from my flower shop.

hi Mr Tan,
Thanks for the payment. By the way, there is a mistake with Mrs Y's address (7 instead of 3). When our delivery man found out the mistake, he went to buy 4D (Singapore Sweep Draw on 6 Feb - day of delivery) using all the numbers of the 3 addresses - 3730

Mr H, 3 xxxxxxxxxxx
Mrs Y 7 (you gave us 3) xxxxxxxxx
Dr K 30 xxxxxxxxx

The first prize was 3330 - the wrong address you wrote!
What a story...
