GAS LEAK

I am trying to remember what has gone on... Well its been bitterly cold and frozen for weeks with the pipes and ground hard with frost and ice and the duck pond hadn't melted in weeks. We had a gas leak from the big bullet thing that holds all the gas for the cottages, I called the engineer out who said he was busy but can come tomorrow!!! Well he eventually came and established that I wasn't making it up as previously made out to be by the engineer, we in fact did have a gas leak, We have used 6 months supply in only 2 months and he was trying to tell me it wasn't much and shell wouldn't reimburse me...I am at this moment in time...wasting my breath and ink to get some sort of compensation! Its about £600 of gas lost! Doubt if I will get anywhere that's how they make their money! Cynic I am!!
