The delivery was excellent, absolutely brilliant! Your driver was fantastic!


A quick note to let you know that I posted the hole-saw back to you from Stoneville P.O. yesterday. It worked a treat, and the extra 40mm flange was most appreciated. Thank you once again for your generosity. It is gestures like these which give a company a good name. I'll be sure to contribute word-of-mouth recommendations for Coerco.

I am writing to commend your employee, Graeme, who delivered our rainwater and saucer tanks this morning. Not only Did Graeme deliver the tanks on time, he went to the extra mile to place the tanks in their pre-pared locations. This included crossing a boggy creek through rough, granite country. It is so refreshing to receive great customer service these days. Coerco is fortunate to have an employee as competent and helpful as Graeme. He is a credit to your business. Please forward this to the Manager of Coerco. PS Thank you very much for holding our tanks until we were ready to receive them at our farm. It was a great help to us. We will certainly recommend Coerco to our friends and look forward to doing business with you again in the future.
