If it’s inside your kitchen cupboard, I reckon it’s between you and your gas company.
The OC shouldn’t be considered a ‘bank’ provided the damage was not done by their actions but it sounds like you’re very quick to ask them to pay rather than your gas company!
The provision of gas to your apartment is usually the responsibility of your gas company… Have you asked them to fix ‘their’ equipment being the gas meter?
Surely your OC aren’t measuring your gas usage and billing you for it every quarter?
sorry, not trying to be harsh but it I was a member of your OC I would not be happy your asking me to pay, through levies, for something I cannot control!
