I bought curtains for bifold windows. They are very heavy due to the size. They were installed on 31 march and today they fell down and pulled small holes of plaster to the floor. The poll tract that Hilary’s charged £150 also bent due to weight of curtains. Would this be covered by Hilary’s guarantee will they come and replace them? Is this considered a fault. Surely if the curtains are too heavy for the pole etc they should advise ? Thanks
