Literally the worst oil service in my 20+ years of deliveries. We had a delivery of oil, and the incredibly rude driver stated that our tank didn’t meet regulations. Absolutely no idea where that came from, as Certas have many deliveries to our home with no issues since our tank was upgraded several years ago. My mother went into the house to retrieve the certificate showing our OFTEC compliance, but before she could return (about 2 minutes), the driver drove off. I literally ran down our street to try and show the driver the required documents, only for him to ignore them and simply tell me that he’d “explained why he couldn’t deliver and wouldn’t explain again. And the delivery wouldn’t even put a dent in your tank.” I was on with someone from their customer support center as he was driving off - they hung up on me midway through the call when I asked if they could tell the driver that it was okay to make the delivery. To top it all off, we were going through the paperwork and it turned out that the company who’d installed our tank was recommended by..... Certas! We’re not the only people on our streeet who’ve had issues with this company in the last 2 weeks. They tried to deny a topup to a family with young kids at the end of the road due to “overgrown vegetation”, until the dad argued their case for literally 40 minutes. As well as this, they refused to deliver on arrival to a widower in his 90s for similar spurious reasons, leaving him with an empty tank during subzero temperatures. The behavior of these charlatans is absolutely despicable. I wouldn’t be surprised if they’re trying to cancel orders on delivery so the oil can be resold to someone else at a much higher price. The final blow was when we got a call back this morning from their head office. Apparently we had "chased him" and he "felt threatened”- what the driver should have said is we asked him to inspect the necessary documents and ran after him to try to get him to look at them after he refused to inspect them and incorrectly denied us a delivery! We’re in the process of filing a complaint with the appropriate authority after this shambolic service. There are other oil providers out there - for the good of your sanity, use them instead
