Shell Energy are thieves! Upped my DD £40 to £152 without my permission, which I can’t afford. It’s just me, one. Advised them of this, called and amended the DD. I have £235 in credit on my Shell account which they used to cover the bill of £152 from and then, decided to reverse it & keep attempting the direct debit! They don’t care about you as a customer, just want to take as much money from you as they can. Amassing your money in the credit which they don’t even want you to use. So hard to lower your direct debit or use your credit or even get it refunded to you! I have about 3 complaints on my file, worse customer service each month. I would use another company. My customer service agent today heavily insisted that I close my complaints because they helped and advised me sufficiently (in their opinion), despite me being clearly upset that my previous issues hadn’t been resolved nor had the issues today. I literally cannot afford to pay the £152 and begged them to use the credit & stop taking the DD from my account as the bank charges £10 for insufficient funds. Shell do not care.
