Once you catch by this company by any chance... you are in big... big... trouble... I have had gone through all these bad time with them last few weeks... 1) You alway demanded to call them... be prepare to wait more than 20 or 30 minutes and having enough credit or minutes in your mobile if use) 2) Even sometimes you are in middle of conversation, if they knew you are loosing (switching) they will intentionlly hang up (morethan two times)... 2) call again... wait again... even the most disgussing thing with British gas was that sometimes there was female's sexy voice recorded in their waiting tone... Totally disgussing ! 3) Once they blocked you to switch to other company, sametime, they will block you to make online account to pay thier bills... because they put us more stress and time waste by call payment. 4) When they knew you are switching, they will switch you to multiple staff. Simply making you give up (more than 6 staffs... prepared to stay with them at least 2 hours) 5) Even you are totally agree to switch to other company... they will not agree with other company for helping to switch you 6) Lastly, there are exceptially expensive.... everyone knows that...
