Skipton shop owners are baffled by two electricity bills from a company with which, they claim, they have never signed a contract.

Bob and Eileen Wright, of the Wright Wine Company, have received bills from Enron Direct Ltd at the same time as having quarterly bills from Yorkshire Electricity, their regular supplier.

When the Herald approached Enron, an Oxford-based company, it was told that a contract had been signed and it had been supplying the shop with electricity since April.

A copy of the contract has Mrs Wright's signature on the bottom but she still maintains she never signed anything.

She said she did remember a saleswoman coming to shop.

"I am convinced in my own mind that it was something to say that she had been," she added.

Mr Wright added: "We have never agreed anything with these people, it is absolutely crazy."

What the couple found even more puzzling about the contract was that the name and address had not been filled in by Mrs Wright. Instead her name had been printed as 'Elaine Wright'.

The couple received no contract paperwork and were not aware of the situation until a woman at Yorkshire Electricity phoned to say she was sorry they had changed their supplier.

Mrs Wright told her she knew nothing about it and was "gobsmacked" when she was told about the Enron contract.

Julia Brown, account manager from Yorkshire Electricity, said she would cancel the Enron contract and send her a new form to renew the YE contract.

Mrs Brown added: "In previous cases where Enron has been the other supplier we have put in an objection to the transfer at the customer's request but they continued to proceed."

She said an application had been submitted to terminate the contract but her records still showed it existed.

She added that no information had been passed to Enron to help with meter readings.

Mr Wright said he had returned both bills via fax to Enron and had received one letter, saying the matter was being investigated.

However, this week Enron Direct replied to Mr and Mrs Wright saying it was obvious confusion had arisen and the matter would be resolved.

A spokesman said: "Each week, Enron Direct begins supplying electricity to over 2,500 new customers - a process which usually involves transferring accounts from former suppliers.

"It is clear that in the case of Wright Wines in Skipton, some confusion has arisen.

"Unfortunately the customer has been incorrectly invoiced by us even though the account had not been transferred.

"We have already withdrawn these charges, informed Mr and Mrs Wright and apologised to them for any inconvenience.

"As Mr Wright indicated he would donate the compensation offered to charity, we were pleased to double the sum to £100.

"In addition, we have spoken with the agency which is promoting Enron Direct in that area and steps have been taken to try and ensure similar confusion does not occur again."
