Re: Mis-selling complaint
I am writing about an energy contract that I feel I have been mis-sold.
In my opinion, I was mis-sold the contract because:
I was told the tariff price was cheaper than our current suppliers but this isn’t the case. I agreed to the contract on 10 June and found this out a week later.
Please reply in writing within [number of days] working days.
Thank you.
Yours faithfully,
[complainant name]
