What a shame! Altons have been excellent over the years but not today. Purchased an expensive BBQ from them recently and said that I would need a Green 13KG bottle. Tried to fit the bottle but it was far to big and clearly only takes 5KG. Went back to Altons to change it over for 2 x 5KG bottles as this was promised by the Altons guy who fitted the BBQ for us. Got their today and he wasn't there but no one would change them over just kept telling me to contact CALOR. So now I'm left a 13KG bottle which hasn't been used and no valid gas bottle for mine. Don't say your going to do something then don't honour it! Disgusted!
