in April last year my bill came in as usual but had one difference they had changed the door number from 1 to 3 number 3 had a pay as you go meter, i told them 10 month ago and it has taken 30 hours of phone call 3 complaint that were marked as solve when it was not and now i face a bill even tho no one is living in there for £1500 as i was paying my bill under flat 3 they have now back billed me to April saying i have not paid a bill since that time and they have changed the account number , They are incompetent they customer service is appalling give them a wide berth if you have any sense
