They have failed to deliver my heating oil in the window promised of 14 days from the order. It's now a week after it was due and I've called and emailed them every day but had no reply. I'm getting really worried as my oil is very low. I'm disabled and classed as vulnerable, but they seem to have no way to escalate my complaint, they keep promising to try and get it sorted, and to come back to me with a solution but no one can actually do anything. Useless and heartless. I just don't know what more I can do to get my delivery. If I cancel I'll have to pay a much higher price for an emergency delivery now, I've already spend £30 hanging on trying to get through on their phone line , to no avail.
