I signed up with them a couple of months ago and realised the information on my current tariff with my supplier was incorrect. I contacted their support team several times with the correct information and have been constantly ignored. I suspect the reason they want this information vague or blank is so that when they swap you it looks like a better saving than what it really is. I have tried to cancel my subscription but as you do not have an account with them the only way you can cancel is by email which they have been ignoring. No doubt they will try and switch my energy this month when my current tariff expires which will cause me even more grief having to cancel it all. DO NOT USE
