Awful company. They have really overcharged us but it's impossible to get in contact with them - really long phone queues that cut you off, and a online chat which when you get to the front just sends you to the back. For two people living in a small flat they want to charge a direct debit of £180 a month! This has been creeping up over the year (it started at £60 which is normal) and we have also had large additional bills of over £300. This doesn't seem uncommon either, my friend also had a similar problem with them charging her (also living in a small flat of 2 people) £120 a month. I'm in the process of complaining to the ombudsman about this as we have tried multiple times to resolve this but bulb are not helping at all - to the point the customer service representative on the phone said to just complain to the ombudsman and she wouldn't put me through to discussing with a manager.
