On the 4th of June this year I fixed my tariff with British Gas to their Electric Driver v7 Electricity Only tariff, making use of their competitive rates for charging my EV vehicle overnight...or so I thought! I noticed that while my account online had updated to this tariff, my 'smart meter' was still showing that I was on their Standard Variable tariff. Concerned that I was going to be charged an incorrect amount I contacted British Gas and was advised not to worry about the smart meter because they could see that I was on the selected tariff and my bill would reflect the correct amount. I was advised that my tariff would sort itself out in a few weeks. 3 months later and my smart meter is still showing the incorrect tariff so I contacted British Gas again to be advised that my smart meter was clearly broken and an engineer needed to come out to fix it. What infuriates me more is that on the 1st October when the new energy price cap came into effect and my bill was sent to me a number of things happened: 1. My bill was incorrect and showing that I was on their Standard Variable Tariff. 2. My Direct Debit had been increased without my approval to compensate for the debt that I was supposedly in. 3. My Tariff online had magically changed to the Standard Variable Tariff. I contacted British Gas on a number of occasions through their very unhelpful chat service and their even more unhelpful Customer Services team who feel the need to talk over their customers, inform them that they're lying and tell them that they're wrong. Repeatedly. They also seem to have an inability to transfer phone calls to a customer services manager. I raised two complaints. One complaint for the service I had received and the second complaint for their inability to correct my account, despite me having an e-mail confirmation of my new tariff. I was advised that someone would be in touch within 10-14 Days. This didn't happen. I spoke to them via their chat system on consecutive days and was advised that my case handler would be in touch within 24 hours. This didn't happen. I called them and complained, I was advised that my case handler would be in touch within 24 hours. This didn't happen. I am still waiting for my case handler to get in touch to resolve my complaint. I have got tired of waiting so I have reported them to the energy ombudsman. It is virtually impossible to speak to anyone that is competent enough to resolve my complaint, nobody at British Gas is prepared to take ownership for their mistake, which they admitted to and nobody at British Gas actually seems to care one bit that they've made significant process failures at their end and haven't updated a customers account to a tariff they have confirmed via e-mail I am on. I feel like British Gas are simply hoping that I give up and the problem goes away because they don't have the intellectual capacity to retrospectively update my bill back to June when I fixed onto a new tariff. I will never use British Gas again and would encourage anyone thinking of switching to them, not to. Pay more for your energy elsewhere if you can get your Electricity from a company that know what they're doing. To British Gas if you bother to read this, I gave you multiple opportunities to fix the issue. I chased you multiple times to fix the issue and you didn't bother.
