Ultratech Cement — RMC

I am in process of constructing a commercial property. As it’s in a busy street we decided to go with Ultratech RMC.
The sales guys promised on time Delivery. To our utter disappointment no one turned up, after lot of follow up the site engineer turns up and he took almost an hour to confirm the go ahead.
The pumps came in very late so did the truck loads. Which resulted in us working late in the night, causing disturbance to the neighbours. Work suppose to commence at 10pm and finish by 11:30pm, started only at 11:20 and finished at 2:30am!!
Uktratech had promised they would keep up the time and ensure help will be on hand to contact. We had to run pillar to post. Sales person switched off the phone and literally no one was there to support.
