Well I'm a buyer like you. And I understand your complaints. But based on your additional comment below, it seems your agent is actually trying to work in your favor. I have had a couple agents who just do not follow-up with me. No calls. In today's real estate market, I have learnt that time is of the essence.
The term "Stalking" sounds to me like your agent is trying to avoid this deal from slipping through your hands. In today's real estate market, and trust me I have been searching for about a year, you have to act fast & a verbal agreement does not mean much. Your agent is probably trying to get an actual contract asap & will need your lawyer/attorney's information in order to send d contract over. Especially if this is a REO or foreclosure, you have only a few days to get the inspection done & sign the contract. Or else, another person's offer can still be accepted.
Believe me when I say that this rule was not set by your agent, he/she knows the game and is only trying to abide by it. Today's market needs an aggressive agent (and your agent seems like one).
If there are other reasons why you are dissatisfied with your agent, then you should speak with the broker's manager. If not, then you probably should refer me to him/her, as I could use a more aggressive agent myself. All the best in your purchase!
