Periodically there are posts on here from a punter exasperated at trying to message a particular SP with no response. The simple answer is that many (most?) SPs just don't spend the time online to respond to all the AW messages they get. You are treating it as a one-one conversation, as far as she is concerned you are just one out of hundreds of messages she has received that day, most from people who will never show up and are just time wasters. If she has given a phone number, texting or calling is far more likely to get a response. If the phone number is not shown, then it is likely that she is not currently working. There are a few SPs that insist you message them in order to get their phone number, but in my experience they are very few, and tend to explicitly state that in their profile. Texting or calling shows that you are more likely to be a genuine customer, rather than someone wanking their way through the AW listings.
