Hi, I wish to raise a complaint. I paid extra to ensure an oil delivery by 8 March. It did not arrive and I was not notified. I had to call and email to raise the issue and was told it would be expedited. It was not and did not arrive on 9, 10 or 11 March. No contact from yourselves. I called and emailed again on 12 March to be told it had been routed out and asked for a complaint to be raised. Oil level was below the sight tube by this time causing great distress. I am looking for compensation for late delivery and lack of contact by Certas and the distress caused.
