i ordered 600 litres of oil with boiler juice, and 2 days later got a text from Certas to say they would be delivering i phoned them to say that i would not be home that day, then received a text from Boiler juice to say certas energy had delivered 1 litre of oil which is impossible !!! i then phoned boiler juice to say nothing had been delivered and they say the problem is with certas and not them even though i paid Boiler Juice, they now have cancelled my order, i called to say please redeliver and they said they couldn't and i had to pay another £80.00 to place another order as oil had gone up!!! in the meantime i still haven't received my refund, so cannot order any more oil until i get this refund!! DO NOT USE THIS COMPANY !!!
