Arguably the worst customer service of all time, and that's up against some pretty stiff competition (I used to have AOL as my ISP). Yes they have actually got some staff in an Indian call centre now that do actually answer the phones, but for all the use it will do you may as well speak to the next door neighbours cat. Having finally got my smart meters fitted after 18 months of shenanigans, it transpires that only the electric meters work, the gas meters won't update and as a result all gas meter billing is based on an estimate on a gas meter that was taken out 4 months ago. I have managed to speak to someone about this and was informed that there is a 'Data Issue' will all gas meters and they have no idea how long this will take to resolve. So I am guessing that I am not the only person in this situation. You would have thought that the sensible thing to do would be to put a statement to this effect on the website or in the FAQ or Facebook page. But so far I have no been able to find anything to tell customers that their smart meters won't work and their bills will be pure guesswork. I would cancel my contract but how am I supposed to get final readings ? Avoid at all costs.
