Impressive customer service

I had purchased 2 x 19kg gas cylinders from Progas and fund that 1 bottle lasted me only 2 months. With my limited knowledge, I suspected it was a cylinder leak but could not confirm until I had used the 2nd bottle. Daphne from Progas had sent out a technician Greg to assist me with pinpointing the issue which he had resolved by replacing a rubber on my pipeline and no fault of the cylinder. Impressive customer service which I was not billed for. Highly recommended.
