Need help with realtor issue, stuck on third property.

[Charles Clingan]

I have sold 2 property's using great agents in 2 different states in the last 4 years. I am now on my third property and with a second agent that appears to be even worse than the first one. There has been 5 times that my listing agent is representing the potential buyer and calls or messages me asking "if I would show the property", isn't it his job to show the property for earning his commission?. Also does not call or message when there has been cancellations. I have other properties that I am interested in buying BUT I am a cash buyer and need the sale of my current property to reinvest. I am currently waiting as I write this if todays showing which is over an hour late is a "go or not." Any advice on how to deal with this current agent? I'm still stuck for another 3 months on the contract with this agent.
