Warning - Please stay away from this company Please listen to my warning and do not use this company. They are utterly incompetent, and the customer service is terrible. Here’s what has happened to me (sorry it’s long): Moved into my current rented property in December 2018 and received letters from Spark Energy and another company both claiming to be my supplier for gas. After many phone calls, emails and a lot of investigation on my part I discovered that someone (most likely the previous tennant) requested the supply be moved to Spark shortly before we moved in. The electric was changed over fine, but the wrong gas meter was changed over. An understandable enough mistake to make given there are 3 flats in my building, however, to this date Spark energy have failed to fix the problem. This has been costing me money, time and is an ongoing stress. For a long time, Spark denied that any mistake had been made despite having been provided with the correct meter number by me which didn't match their details. I continued to try and speak to Spark about the problem. Every time someone would say they were making notes and someone would contact me again soon – but they never did. I would then have to call again to chase up only to find no notes had been left and have to explain the situation again. This continued for months. I provided copies of the letters I had from the other company with our meter number, screenshots of records I found online and photo’s of the actual meter after completing a burns test. Still Spark have not fixed the problem. When I very first spoke to Spark, I set up a monthly DD of £50 per month for gas and electric. Due to us not being able to supply a meter reading Spark advised they would increase our direct debit. I called them, explained (again) and was assured no changes would be made. This happened several more times, then, Spark increased my payment to £150 without providing any notice. When calling them to discuss this I was told they would not refund the additional payment they had taken and would also not reduce it to our previously agreed amount. As a result of the massive increase I cancelled my DD but have continued to pay our agreed £50 as a card payment each month. While they aren’t actually supplying the gas, they are supplying the electric so I think it’s fair to pay for that service. Spark have chased me for what they feel is an outstanding payment for the rest. This involves text messages twice a day, an email once a day and an automated voice call a couple of times a week. It is utterly infuriating that they feel they can harass me for a debt relating to a service they have not been supplying and have failed to fix for a year and a half! I called (yet again) to talk about the problem and Spark did agree that I shouldn’t be chased for any payment until this was resolved. The chasing did stop for about a month but has now resumed out of nowhere. I emailed them again last week but haven’t received a response. I desperately want to move away from this terrible company but can’t until the national database has been correctly updated. At this stage I feel Spark are simply not updating this in order to extract more money from me. I am currently gathering copies of my correspondence together to make a complaint to the Energy Ombudsman to see if they can help me resolve this once and for all. Please save yourself time, energy and stress and DO NOT USE SPARK ENERGY
