Customer Service and Reliability
The review from Nathan Birch highlights the excellent customer service and reliability of the company. According to Nathan, Steve and Paul saved the day by drilling 5 holes at short notice, arriving on site and on time, and providing a great price for their services. They were also professional and knowledgeable in their work.
Safety Concerns
On the other hand, Jeanie Stevens had a negative experience with one of the company's utility drivers. She reported that the driver overtook her at high speed on the wrong side of the road, using the parking lane to pass her near Coles Express on Main South Road. The driver then continued to drive recklessly through Old Reynella and turned left onto Kenihans Road.
