@Andy Zapata Did you find a cleaning service?

The cancel function is not working and I was forced to pay over 400 for service I did not want.There is no customer service number to call.

If you think this distinction is unimportant, consider what happened to investors who placed their IRA funds with American Pension Services,—an administrator whose founder mishandled their money causing a $22 million loss.

Rentvine's excellent customer service spoils me, and I can't imagine using software with lousy customer service. 

If you're anything like me, customer service is the main draw for me when I am choosing any service provider.Look at websites, reviews and testimonials.

Quote from @Patrick Henry: I'm trying to find a few individuals who have use Delta Build Services,  and/or Build 2 rent.

This is not only my experience, but when you call VRBO or Airbnb customer service, they will tell you the same thing.  

I’m on the verge of giving Booking.com the boot , too many cancellations and the worst part is when you call customer service, which is China ….in order to validate you as a host they give you a call back so you can’t get your answer quickly and the callback takes a few minutes and half the time the call does not make it through- enough to make you wanna scream.

The other concern I have is service life. 

And the only "client" reviews I've seen mention that their customer service is non responsive and difficult to get a hold of once you're purchased their services.
