Absolutely appalling! Countless hours on the telephone and no one can help. We've been ping-ponged from one department to another - the only thing we've asked is for them to send someone to replace our prepayment gas meter battery. Turns out they can't do that unless we have an account. To create an account they send us to a line that hung up on us 5 times. The account couldn't be created initially because our address is not in their data-base (the only one in this block of flats?!). After finally creating an account they said they would send someone within 4 hours. 6 hours passed and when we called again...turns out no account was created. Did I mention it's February, we're freezing, we can't cook food or have a shower? Not that they care...
