My experience of dealing with British Gas is similar to that of Mrs N Allen (Opinion, July 5).

There is a need to contact them, so you phone. The first person you speak to will "put you through". That is the end of it. There is a ringing tone but no one answers it.

A fault that needed rectifying, at my request, brought forth two "engineers". They obviously did not know what to do or where to start. After a long time of trial and error, the fault was put right. A large bill resulted.

Another of the many instances of my frustration with British Gas was when I wrote asking for details of a service it was advertising. What I got in reply was a bill for the service about which I was inquiring. True, the company apologised and cancelled the bill but offered no compensation for my having had to write in.

The only answer is to change suppliers, which I have done and, so far, all seems to be satisfactory.
