Was in Sainsbury the other week and approached by a lady advising me about Sainsbury/EDF energy for gas and electric. She sounded convincing so I signed up with them. Since then they have sent me a few letters and advised me that I start my contract with them on 27th July even though I have yet to give them meter readings or meter numbers. I have also had an e mail from my existing supplier Scottish Power saying they are sorry to lose me and if I want to stay with them to ring this number blah blah. After hearing of their huge price increase i rang them this am to say I did noty want to go with them now, the advisor told me that I have to stay with them until I switch suppliers again. She advised me that the cooling off period had expired. I said that I felt I should have been told of their impending increase and she pooh poohed this and said they did not know about it - yeah!!! I am now awaiting to spk to Scottish Power to see what they say. Can anyone tell me whether I have to stay with EDF even though they do not have my meter numbers am I liable to stay with them!!!!
