Left British gas 2nd february to join smaller energy supplier bulb who are fantastic. I was told i would receive my final bill within 6 weeks but it arrived within 2 days .Paid over the internet but found out they took the payment twice. Rang them up over 4 weeks ago about this and they said they would send cheque out within 5-10 days . Did not arrive so have rang them back numerous times only to find out on the first occasion it had not been sent and now they are putting the blame on royal mail. Funny how when you owe them money they want it next day but when we are owed it it takes forever. Customer service is shocking. Do not seem to know what they are talking about . Also my bills were going to double but thanks to bulb I will be saving over £500 a year. These big firms have exploited us for years . My advice have a look at smaller suppliers especially bulb.
