The comma is increasingly acceptable, after 'and'.
However, as an English teacher, I would not accept two whole sentences separated by a comma. You should have a full stop for two separate and complete sentences.
Alternatively, use a semi-colon for two related sentences, said with a briefer pause, like this:
'My surname is Wang. What's your last name?' Alternatively,
'My surname is Wang; what's your last name?'
