Started to receive monthly gas bill for only £15 thought obviously this wasn’t correct so phoned up last October after 40mins on the phone speaking to a foreign lady the phone was cut off .Phoned the following week and was told that we were £600 in credit because we were being taken off the old computer system and would be put on the new computer system.When on the new system we would then have the £600 to pay our gas usage.After heaven knows how many times we have emailed British Gas to find out what we owe in gas usage,we have been told that our query has been sent to the gas complaints team who will sort this out.This has now been going on for five months why is this taken so long .?British gas are an absolute joke .Now going to get help from the energy ombudsman hopefully they have better luck than us.
