Worst customer service I have ever had to deal with. Been a customer for several years no problems. Recently received a letter stating I owe them £825 in debt which they will begin taking at £28 a month. This confused me as I have only ever been a prepayment meter customer. I have never had an account that could go into debt in the first place. Definite error. Emailed their complaints team with all relevant details for ID and explained I am a disabled customer on benefits and have no means to call them as i can't afford credit at the moment. 4 days later a reply says I need to call in ty goodbye. Replied the obvious. 3 days later I'm asked to provide info for ID purposes ty goodbye. Replied with said info Again. 2 days later I'm asked for the info from the screens on my meter. No explanation of how to get them. 3 days later I'm told how and provide pics of those screens. A week passes so I email for an update and I'm told I need to call in because it does appear there is a debt on my meter.... Honestly. The worst. Company. Ever. I am sick of being fobbed off with a 1 sentence email so some overworked peon can say he actioned a complaint. I will be looking into legal action because this is honestly robbery. I'm being told "You owe us £825 But we don't know why. You have to call us to fix it" and good luck with that when it's a 30min call queue every damned time you manage to borrow a phone. Never been more infuriated by a company in 39 years on this planet.
