Recent research, conducted by Which?, Â has found that four out of ten people weren't happy with their energy supplier, according to an article published by the Telegraph.
Amongst the most common problems that led to complaints included mistakes featured on bills, meter readings that were not accurate and significant spike in energy prices.
Which?'s research also revealed that around nine out of ten complaints that hadn't been resolved were not taken to the energy ombudsman.
More surprisingly the research found that a fifth of those surveyed, who encountered problems with their supplier, stated that they decided not to make any complaint.
The results provided by the research were gathered during the 12 months leading up to September of last year.
Executive director at Which?, Richard Lloyd, said: "Energy suppliers should be held publicly accountable, on a regular basis, for putting right the problems their customers are reporting.
"It is a sign of the level of frustration with this industry that so many people have a problem but don't complain , even when they could b missing out on compensation."
