Builders warehouse disgusting service

Builders warehouse has the worst customer service I have received from any hardware in my life, I do not complain but now I have had it!!! I have been to 3 different builders warehouse in the past month and the service is all the same "utterly disgusting". I would NOT recommend anyone to builders warehouse rather go to a different hardware. I would rather pay more and get service from someone else then come back to no service or utterly disgusting service.
