Disgusting Customer Service

After having waitied for my Crusher Sand to be delivered for over 3 hours (they had contacted me informing me that the driver was on his way) I asked to speak to the manager. I was provided with his contact details (THEO - Newcastle Branch Manager) and in my frustrated state called him only to be sworn at!!! In a raised voice he said "Do not ****EN talk to me like I'm your ***, I'm not your ****EN ***, don't you dare ever ****EN talk to me like that"... Now I don't know if Ni-Da Staff aren't trained on customer service but that is not the way you talk to a customer, especially when you and your team of employees are on the wrong, but regardless, you never ever handle a customer complaint like that. I defintely am disgusted by the way he handled my complaint.
