Just a quick note to thank Leah for all her help with our order of 3 Polymaster tanks. Especially in getting them here today which I know was a stretch but it was really important to get them filled before the January hot weather impacts on our spring.
Well done to the whole team and to please pass on our thanks especially to Michael who did a sterling job with getting the tanks into position in 3 different location and driving all the way from Swan Hill today.

Thanks for the great service and providing a quality tank. Ben your truck driver was also a legend in how he delivered the tank - positioning it perfectly for such a large tank.

We particularly wanted to compliment your delivery driver Ben for an excellent job.
We found him to be immensely obliging and he kept us updated regarding ETC beforehand. Also, he’s incredibly adept at getting his truck positioned and the tanks handled for a perfect landing onto their bases.
A first class job, and quite a credit to Polymaster. Please pass on our thanks to him, as well as Emma and all the others who made it happen.
We’re a couple of very happy Polymaster customers.
