It's very possible the one you communicated with is on vacation or out of the office.
Although it's the HR's job to handle all kinds of questions you might have, they have to deal with lots of people/issues not just ONLY you. When you asked something if they don't have immediate answer meaning they are trying to find one or just get distracted.
If they decided to cancel the offer, they will let you know. If you really need to talk to someone, try the HR manager or your manager. They will direct you to someone for answer if they couldn't answer your questions.STOP worrying.
