No more Mica Hardware for me

I was so disappointed with the service I got at Airfield Mica Hardware in Springs. I bought a 3KG gas cylinder and I requested it to be filled which I paid for that. It never lasted even few hours. I went to the store to lay a complain and the store manager never even bothered to listen to my problem. What pains me the most is that I passed so many places which sells gas cylinders and trusted Airfield Mica Hardware with my money and not only that to get there from place is about 50kms which means I lost double. I refilled it somewhere and it lasted for a week. Apparently where I refilled they told me the reason why it never lasted. This guy said a new cylinder is normally having air inside so that air needs to be released before it can be filled up.
