Shocking response to poor gas bottle installation

I have been purchasing gas from The Gas Boys for a few years with absolutely no problems. Until this month. I have my receipts for the past 2 years and 1 x 9kg bottle lasts me 6 months.

On the 28/03/21 I had my new bottle installed. I noticed a gas smell but thought nothing of it. I admit I was lax in not investigating the gas smell more, as it was stronger than normal. Two weeks ago I suffered from a bad case of what my doctor told me was Vertigo. I was nauseous and very dizzy. I didn't connect the dots, that it could possibly be the leaking gas. I contacted Gas Boys to assist and check but no one was available. I then called a friend to come and check the connection and he found a bit of the wrapping in the thread of the gas bottle. This explained the leaking gas smell. I then left it and carried on. The gas smell had disappeared and it was working fine.

This morning, my gas ran out. It's exactly 1 month from the day of purchase. I was shocked. I placed a call to The Gas Boys telling them what had happened and I expected them to apologise for the poor installation and offer a replacement bottle. I am most certainly not trying to score a free bottle here. It's the principle of good customer care and relationship. I was told that they would not offer to replace it, and perhaps the problem was on my side i.e. the connection.

I feel this is in extremely poor taste. For R259.00 they are happy to lose a customer through lack of concern. I'm quite shocked to be honest. Leaking gas is a safety risk! I will certainly go elsewhere for my gas from no on.
