Signed a buyers agent contract do I have to use the agent

[Matt Arden]

Hello I was wondering if I signed a buyers agent contract does that mean I have to use that agent to buy in that town or city. When I signed the contract everything was going good responding to my calls and text after about 2 weeks and 1 offer does not get back to me and when she does she will text me and I will text her right back and won't get a reply for the rest of the day. I think they are a part agent and have a job doing something else. I still want to buy in this town but don't want to get sued or in trouble any advice will help thanks.
