In particular, that we delivered a quality product that finished on time and within budget. As a Principal Contractor, we understand that we are only as good as our Subcontractors. Its only with the help of skilled and collaborative businesses like yours that we are able to deliver projects in the manner that we do. On behalf of Lipman I want to thank you and your team for their effort on this project. I hope to see you on the next one.

Most of us would have to admit that we’ve had our share of mediocre service from companies in the past. However, some companies are starting to "get it". They realise that in today's global marketplace, consumers have a greater number of choices than ever, therefore they are providing better buying experiences for customers to inspire loyalty, rather than depending on fancy schmancy ad campaigns. So on behalf of Virgin Active Norwest I just wanted to pass on a big thanks to our air conditioning service provider CREST. You have been instrumental in providing quality service at all times and as operations manager for this proud health club, I could not ask for more from your entire team, whether it is your service technician Prav being pro-active in all his work or the service team and yourself responding to all of our issues in a timely problem free manor. Thank you for your support, it is greatly appreciated.

Operations Manager / Virgin Active Norwest
