I would give zero stars if possible, The delivery company delivred the product to the wrong address dropping a package marked "fragile" over a five foot gate to be left for five hours in the rain. When I complained to your agent, Hamilton Gas Products, they were unsympathetic and insisted I must check the product immediately as any damage has to be reported within 24 hours under terms and conditions, which was not possible for me at that time. The mis-delivery was dismissed as unimportant. In future I will be avoiding Calor products and certainly Hamilton Gas.
