What gave you the impression this was a Government helpline, when the above quote is displayed at the top of their home page.?
.......................................................
I believe your association with this company should have ended and not have proceeded any further when they requested your card details.!
You need to carefully read the bullet number 8 in their terms and conditions copy below, which incidentally are identical to the terms and conditions displayed on the ihelpline.com site.......you need to pay urgent attention to this clause...it gives them the entitlement to keep making continuous membership deductions until you cancel. Cancel straight away.!
Cancellation 8.
Our contracts are for subscription periods of thirty days or twelve months and are renewed automatically by us unless you cancel your agreement before the renewal date. You can cancel your agreement at any time but it will take not less than twenty four hours to process your request for cancellation. You will not be entitled to any refund for any part of an 'unused' subscription. If you are offered free support for example for the first month but then decide to cancel your subscription your support will be cancelled immediately. If however you subscribe for our service for thirty days and then cancel before the end of the thirty days you will receive our support for the remainder of the thirty day period.
