Ordered home heating oil on the Tuesday of first week in December with delivery LATEST Tuesday 20th. ( I hasten to add that for over 20 years I have ordered oil via Mole Valley Farmers without a single hitch and none of the following is down to them) 10am Tuesday 20th got a phone call from Certas to say delivery was delayed and the caller could not give me any information as to why the delay or when delivery might take place. Tried contacting Certas on Wednesday 28th without success and it was clear no one was going to pick up my call. Got Mole Valley involved and within an hour they confirmed Certas would deliver by Friday 30th LATEST. NO delivery and no phone call so this afternoon MV cancelled the order and placed it with another supplier for Wednesday 4th. Certas claims to be the UK's largest supplier of oil and if the company continues this level of service it won't be long before it is the SMALLEST and the management should be shamed of themselves. I strongly recommend that you one avoids using this outfit as service is non-existent. Thank you Certas for a cold Christmas and what will be a cold New Year
